or REM sleep, is a unique phase of mammalian sleep
characterized by random movement of the eyes, low muscle tone throughout
the body, and the propensity of the sleeper to dream
. This phase is also known as paradoxical sleep (PS) and
sometimes desynchronized sleep because of physiological similarities to
waking states, including rapid, low-voltage desynchronized brain waves.
Electrical and chemical activity regulating this phase seems to originate
in the brain stem and is characterized most notably by an abundance of the
neurotransmitter acetylcholine, combined with a nearly complete absence of
monoamine neurotransmitters histamine, serotonin, and norepinepherine. The
cortical and thalamic neurons of the waking or paradoxically sleeping
brain are more depolarized—i.e., can "fire" more readily—than in the
deeply sleeping brain. The right and left hemispheres of the brain are
more coherent in REM sleep, especially during lucid dreams

is when the EEG
activity is synchronized,
producing slow waves with a frequency of less than 1 Hz and a relatively
high amplitude. The first section of the wave signifies a down state,
which is an inhibition period in which the neurons in the neocortex are
silent. This is the period when the neocortical neurons are able to rest.
The second section of the wave signifies an up state, which is an
excitation period in which the neurons fire briefly at a high rate. The
former state is a hyperpolarizing phase and the latter is a depolarizing
phase. The principal characteristics during slow-wave sleep that contrast
with REM sleep are moderate muscle tone, slow or absent eye movement, and
lack of genital activity.

communicate effectively with those around you. Sleep loss can reduce your
motivation to engage in physical exercise as well. You also might
experience decreased coordination and poor physical performance, which can
compromise your physical readiness and affect injury risk. Sleep impacts
your eating habits too. You’re more likely to crave unhealthy foods when
you’re operating in a sleep deficit. Sleep deprivation can increase your
risk of diabetes, higher body mass index (BMI), and hormonal imbalances

a burst of oscillatory brain activity visible on an EEG that occurs during
stage 2 sleep. It consists of
waves that occur for at least 0.5 seconds. Sleep spindles are
generated in the reticular nucleus of the thalamus. Sleep spindles
(sometimes referred to as "sigma bands" or "sigma waves") may represent
periods where the brain is inhibiting processing to keep the sleeper in a
tranquil state. Along with K-complexes they are defining characteristics
of, and indicate the onset of, stage 2 sleep. They are often tapered at
both ends and frequently seen over the frontal and central head regions.
They may or may not be synchronous, but they should be symmetrical and
bilateral. During sleep these spindles are seen in the brain as a burst of
activity immediately following muscle twitching. Researchers think the
brain, particularly in the young, is learning about what nerves control
what specific muscles when asleep. Spindles generated in the thalamus have
been shown to aid sleeping in the presence of disruptive external sounds.
A correlation has been found between the amount of brainwave activity in
the thalamus and a sleeper's ability to maintain tranquility. Sleep
spindles result from interactions between cells in the thalamus and the
cortex. Sleep spindle activity has furthermore been found to be associated
with the integration of new information into existing knowledge as well as
directed remembering and forgetting (fast sleep spindles). During NREM
sleep, the brain waves produced by people with schizophrenia lack the
normal pattern of slow and fast spindles. Loss of sleep spindles are also
a feature of familial fatal insomnia, a prion disease. Changes in spindle
density are also observed in disorders such as epilepsy and autism.

Delayed Sleep Phase Disorder
is a chronic dysregulation of a
person's circadian rhythm (biological clock), compared to the general
population and relative to societal norms. The disorder affects the timing
of sleep, peak period of alertness, the core body temperature rhythm, and
hormonal and other daily cycles. People with DSPD generally fall asleep
some hours after midnight and have difficulty waking up in the morning.
People with DSPD probably have a circadian period significantly longer
than 24 hours. Depending on the severity, the symptoms can be managed to a
greater or lesser degree, but no cure is known
Advanced Sleep Phase Disorder

patients feel very sleepy and go to bed early in the evening (e.g.
6:00–8:00 p.m.) and wake up very early in the morning (e.g. around 3:00
is when an attempt is made to move bedtime and rising time later
and later each day, around the clock, until a person is sleeping on a
normal schedule. This treatment can be used by people with delayed sleep
phase disorder who generally cannot reset their circadian rhythm by moving
their bedtime and rising time earlier.
Shift Work Sleep Disorder

excessive sleepiness affecting people whose work hours overlap with the
typical sleep period. There are numerous shift work schedules, and they
may be permanent, intermittent, or rotating; consequently, the
manifestations of SWSD are quite variable.

characterized by pauses in breathing or periods of shallow breathing
during sleep. Each pause can last for a few seconds to several minutes and
they happen many times a night. In the most common form this follows loud
snoring. There may be a choking or snorting sound as breathing resumes. As
it disrupts normal sleep, those affected are often sleepy or tired during
the day. In children it may cause problems in school or hyperactivity.
Obstructive Sleep Apnea
is the most common type of sleep apnea and is
caused by complete or partial obstructions of the upper airway. It is
characterized by repetitive episodes of shallow or paused breathing during
sleep, despite the effort to breathe, and is usually associated with a
reduction in blood oxygen saturation. These episodes of decreased
breathing, called "apneas" (literally, "without breath"), typically last
20 to 40 seconds.

asleep or awakening, briefly experiences an inability to move, speak, or
react. This is a transitional state between wakefulness and sleep,
characterized by an inability to move muscles. It is often accompanied by
terrifying hallucinations to which one is unable to react due to
paralysis, and physical experiences (such as strong current running
through the upper body). These hallucinations often involve a person or
supernatural creature suffocating or terrifying the individual,
accompanied by a feeling of pressure on one's chest and difficulty
breathing. Another common hallucination type involves intruders (human or
supernatural) entering one's room or lurking outside one's window,
accompanied by a feeling of dread.

recent study done at Louisiana University, has been shown to
increase sleep, because of its melatonin content as well as
phytonutrients that inhibit the breakdown of tryptophan. I also
include a banana which contains tryptophan, magnesium, potassium
and vitamin B6 (Pyridoxine). Tryptophan is converted to
serotonin and melatonin. Magnesium and potassium relax muscle
and nerve cells and B6 is necessary for the conversion of
tryptophan into serotonin. I add some almond milk for more
tryptophan and magnesium. Lastly, some flaxseed for omega 3’s

Magnesium is known as the anti-stress, anti-anxiety mineral
and is a natural sleep aid. Numerous studies have shown its
effectiveness in lowering anxiety and reducing stress levels as
well as helping with deeper more restful sleep. Over 75% of
women do not get their recommended daily allowance of this
mineral which is a co-factor in 700-800 enzyme reactions in the
A magnesium deficiency can magnify stress and anxiety making it
harder to go to sleep and stay asleep. Serotonin, the feel good
brain chemical that is boosted artificially by some medications,
depends on magnesium for its production and function.
Not all forms of magnesium are easily absorbed by the body.
Magnesium citrate powder is a highly absorbable form that can be
mixed with hot or cold water and sipped at work or at home
throughout the day.
Electrical appliances and electromagnetic radiation in the
bedroom is another factor to be aware of that makes falling
asleep and staying asleep more difficult. Keep these to a

night’s sleep. There are many types of temperature regulating clothing
available and various different applications for consumer use.
sleep experts say that a
cool room, somewhere around 65 degrees
, makes for the best sleep, and
research backs this notion. For safety reasons, the American Academy of
Pediatrics recommends babies sleep without any loose blankets, so at night
it's best to choose an outfit that keeps your baby comfortable without
extra layers. Avoid over-bundling your baby: most nights your infant can
wear a onesie and a cotton swaddle, or cotton pajamas with feet. In the
winter, heavier pajamas or an additional sleep sack (a sleeveless,
wearable blanket) will work. Older children tend to kick off their covers
at night, so you may want to dress your toddler or young child in an
outfit that works without blankets as well. Choose pajama fabrics that are
breathable and won't cause your child to sweat during the night. The same
general principle of cool air for better sleep applies to children, so try
to keep the room in the mid-60 degree range.
Shivering and sweating at night
the night, your body uses its own heating and cooling mechanisms to keep
your temperature in a healthy range. But the sensations that come with
this natural "thermoregulation" can make it hard to sleep peacefully. When
your temperature rises, your body produces sweat that is meant to cool you
down as it evaporates off your skin. If the air, your mattress, blankets,
or pajamas keep you too warm, you might find yourself damp and
uncomfortable. And if the room is too humid, sweating may not even cool
you off, since the air is already saturated. On the other hand, if
temperatures get too cool, this will produce a shiver, in which your
muscles contract and expand rapidly to produce heat. Both of these
automatic processes can happen without our conscious knowledge and they
tend to make for restless sleep. For ideas on managing temperature, see
tips for sleeping with hot flashes and cooling the bedroom.
relationship between insomnia and body temperatures
. Sleepiness and
sleep propensity are strongly influenced by our circadian clock as
indicated by many circadian rhythms, most commonly by that of core body
temperature. Sleep is most conducive in the temperature minimum phase, but
is inhibited in a "wake maintenance zone" before the minimum phase, and is
disrupted in a zone following that phase. Different types of insomnia
symptoms have been associated with abnormalities of the body temperature
rhythm. Sleep onset insomnia is associated with a delayed temperature
rhythm presumably, at least partly, because sleep is attempted during a
delayed evening wake maintenance zone. Morning bright light has been used
to phase advance circadian rhythms and successfully treat sleep onset
insomnia. Conversely, early morning awakening insomnia has been associated
with a phase advanced temperature rhythm and has been successfully treated
with the phase delaying effects of evening bright light. Sleep maintenance
insomnia has been associated not with a circadian rhythm timing
abnormality, but with nocturnally elevated core body temperature.
Combination of sleep onset and maintenance insomnia has been associated
with a 24-h elevation of core body temperature supporting the chronic
hyper-arousal model of insomnia. The possibility that these last two types
of insomnia may be related to impaired thermoregulation, particularly a
reduced ability to dissipate body heat from distal skin areas, has not
been consistently supported in laboratory studies. Further studies of
thermoregulation are needed in the typical home environment in which the
insomnia is most evident.

How to Choose the Right Pillow
If you are a stomach sleeper, you
will need a soft, fairly flat
A back sleeper should look for a medium thick pillow. Side sleepers will
need a thicker, firmer pillow to help support the neck. Mixed sleeper and
you find many positions comfortable throughout the night, look for a
pillow that is of medium thickness, and a bit softer so that it can be
used comfortably in different positions. A positional pillow is a lower
case n-shaped pillow that claims to help those with sleep apnea stay in
the ideal position. The pillow also claims to help reduce tossing and
turning throughout the night. Cervical pillows provide extra firmness in
the lower part of the pillow in order to provide support for the neck. The
claim is that these pillows will help reduce neck tension and headaches,
however there has not been sufficient research to back up this claim.
Anti-snore pillows claim to help position the head so that the airways
remain open by lifting the chin away from the chest. Cool pillows are
designed to include fillings that absorb head heat in order to keep you
feeling cool. Although they can be used by anyone who wishes to keep cool
at night, they may be particularly suitable for someone suffering from hot
flashes. Oxygen pillows are designed to promote the circulation of air,
which is meant to help you breathe more freely and deeply while you sleep.
While some claim this has helped relieve pain, doctors are not sure how or
whether or not this technology actually works.

effects the mind and the mind effects the body. So dreams have many
underlying reasons why they are the way there are. maybe emotions are
being used by dreams to increase heart rate and increase breathing, maybe
because of maintenance the body is doing, and so the body tells the brain
that it needs a nightmare to increase the heart rate. Types of dreams are

Rapid Eye Movement
(REM) sleep which occurs after
periods of sleep deprivation. When people have been prevented from
experiencing REM, they take less time than usual to attain the REM state.
When people are unable to obtain an adequate amount of REM sleep, the
pressure to obtain REM sleep builds up. When the subject is able to sleep,
they will spend a higher percentage of the night in REM sleep.
Non-Rapid Eye Movement Sleep
is, collectively, sleep stages 1–3,
previously known as stages 1–4. Rapid eye movement sleep (REM) is not
included. There are distinct electroencephalographic and other
characteristics seen in each stage. Unlike REM sleep, there is usually
little or no eye movement during these stages. Dreaming is rare during
NREM sleep, and muscles are not paralyzed as in REM sleep. People who do
not go through the sleeping stages properly get stuck in NREM sleep, and
because muscles are not paralyzed a person may be able to sleepwalk.
The brain practically shuts off in stages three and four and shifts
into slow-wave sleep, where heart and breathing rates drop dramatically.
Only after 70 minutes of non-REM sleep do we experience our first period
of REM, and it lasts only five minutes. A total non-REM–REM cycle is
90 minutes; this pattern repeats about five times over the course of a
night. As the night progresses, however, non-REM stages shorten and the
REM periods grow, giving us a 40-minute dreamscape just before waking.
Fetuses and babies spend 75 percent of their sleeping time in REM.
Research indicates that people dream 4-6 times per night
during an 8 hour
sleep cycle, with most dreams occurring during “lighter” stages of sleep.
Vitamin B6 could help people to recall their dreams
. Prior to taking
the supplements, many of the participants rarely remembered their dreams,
but they reported improvements by the end of the study. Vitamin B6 did not
affect the vividness, bizarreness or colour of their dreams, and did not
affect other aspects of their sleep patterns. The randomised,
double-blind, placebo-controlled study saw participants taking 240mg of
vitamin B6 immediately before bed. The average person spends around six
years of their lives dreaming. Vitamin B6 occurs naturally in various
foods, including whole grain cereals, legumes, fruits (such as banana and
avocado), vegetables (such as spinach and potato).
Dormio: Interfacing with Dreams to Augment Human Creativity
. Using an
electronic glove that contains sensors to monitor muscle tone, heart rate,
and skin conductance, it monitors when you enter hypnagogia and when
you’re falling into real sleep. At that point, Dormio gently nudges you
with an audio cue emitted from either the team’s smartphone app, or a
nearby Jibo robot with a cue word. The researchers used “fork” or
“rabbit,” but it can be any word. The subtle noise is meant to bring you
back into hypnagogia without completely waking you up, and in fact, the
team found that the chosen word often gets conceptually incorporated into

Dream incubation: ancient techniques of dream influence
My Personal Experience with Dreams
I have been having
all my life. Some of my first memories of dreams
is when I was a little kid and I use to have these recurring
dreams that dinosaurs were chasing me, which was very scary for
a child. The turning point was when I was able to
enough to chase the dinosaurs away with a bat. When I woke
up I was extremely happy. From that point on that made some of
my dreams very interesting to say the least. But more
importantly I realized that some dreams can be controlled, of
course I cannot control everything in my dreams, but some parts I can.
But I still had dreams that I could not control, like the ones
when you're falling off a cliff or a structure, very traumatic.
But luckily I woke up before I hit the ground. My favorite
dream was the flying dream, it was so incredible that you felt
like it was some kind of spiritual awakening. Then the sexual
dreams, some were frustrating and some were just weird, even when I
was able to control the dream I felt like it was not real
enough. I also had those
dreams. Very intense.
Even though the dream seemed so
real, I noticed that the dream was not accurate when it came to
the correct dimensions that are in reality. I also noticed that
is hot I have more violent dreams, I also
experience more sleep
paralysis dreams when my body temperature was hot. And also
noticed that I dreamed less when I was cold
at night. So
body temperature definitely effects your dreams
. This is
probably why sometimes
Hotter temperatures increase violence and crimes
. The high
heat effects our thinking and reasoning abilities, why?
Then around in my 40's (2000-2010
), I started to have
most bazar dreams imaginable
. More incredible then any Hollywood
movie I have ever seen. And the scenes
people could change at any time. I have been wondering lately that some
of my dreams may not be my own, as if they are being sent
while I am in some sort of

much similar, which could allow for some people to transmit and
receive other peoples dreams or thoughts. Just a theory of course but very
interesting. "Maybe the
feeling of receiving signals from
a higher power
is just us receiving messages from each other, or maybe its all
that transmit information. You need a electronic device to see a video
being transmitted but maybe the brain can also interpret these information
signals during sleep brain waves.
I also had these dreams that a dog is
biting my hand, and when I wake up I notice that
My Arm Has Fallen Asleep
. The dream was trying to warn me of
this bad circulation by trying to scare me to wake up using dog
bites. But I'm not scared, I'm more disturbed because I like
Now lately I had a similar dream, but this time it's a
in my bed, and the bear has my entire hand in its
And in the dream the pressure of the bite increases to
the point that I am anticipating the biting to go right through
the bone and bite my hand off, which was the same feeling I had
with the dog bite dreams, but that part has never happened.
And when I finally did wake up I felt really uncomfortable like
something was wrong internally. It was really cold that night and I was
still dressed, maybe
again. Is the animal world trying to communicate
something to me or is my brain just trying to alert me about
some discomfort? I guess it's time for a

years of age.

, I no longer have
these dreams or circulation problems, most likely because I lost weight
and I'm also eating
. I also sleep more on my back now instead of my
side. I still feel some pressure in my chest when sleeping on my side.
I haven't been
for years because I'm not
trying to. Lucid dreaming takes practice and dedication, you
have to consciously say to yourself, "Tonight when I go to sleep
I am going to know when I'm dreaming, and I am going to control
this dream as much as I can." Of course it doesn't work every
time. That's why you have to keep trying and ask every night before
you sleep what you want to accomplish in your dreams tonight. Have a purpose, something that activates the sequence, something
that helps you change from automatic to manual. Like wanting to
kiss a girl in your dream, or stop something violent from
happening, or have a flying dream and not be worried about the
I don't think too much about my dreams, but I
know that you shouldn't ignore your dreams either. Dreams do communicate
something, they all can't just be random non-sense, as crazy as some
dreams are. There must be some reasons why certain dreams are the way they
are. Because some dreams do relate to the waking world in some ways. But
the dream making process is undefined, so it's hard to interpret the
message when you don't know how or why it's made. What are you trying to
tell me dreams? Did someone fall into the well? And how does the brain
know that I'm even going to remember the dream? It's no good sending a
message when I'm not even paying attention. So you must know that I'm
remembering certain dreams. But why? So you see, it's not just a Dream.
Dreams are like a built in entertainment
system that makes sleeping fun
. But who's the director and who's
the writer? And where was I when the decisions where being made about what
the scene was going to be like and who the actors will be. It's like
someone saying action, and you have no idea what's going on because you
never read the script. "So why am I naked?" Lucid
can give you control of your dreams, but lucidity does not
control everything in your dreams, so who or what does?
In dreams I sometimes sense that my

, sleep does more than allow the brain to
rest. It may also aid the consolidation of long-term memories.
REM sleep and slow-wave sleep play different roles in memory
consolidation. REM is associated with the consolidation of nondeclarative
. An example of a
nondeclarative memory would be a task that we can do without consciously
thinking about it, such as riding a bike. Slow-wave, or non-REM (NREM)
sleep, is associated with the consolidation of declarative (explicit)
memories. These are facts that need to be consciously remembered, such as
dates in history.
Brain blocks new memory formation on waking to safeguard the consolidation
of existing memories
BIU study: During consolidation, the brain
produces new proteins that strengthen the fragile memory traces.
Cueing newly learned information in sleep improves memory, and here's how
Memory consolidation is associated with sudden bursts of oscillatory brain
activity, called sleep spindles, which can be visualized and measured on
researchers have found that sleep spindles also play a role in
strengthening new memories when newly learned information is played back
to a person during sleep. Sleep spindles are half-second to two-second
bursts of brain activity, measured in the 10-16 Hertz range on an EEG.
They occur during non-rapid eye movement sleep stages two and three.
Earlier studies had shown that the number of spindles during the night
could predict a person's memory the next day. Experimental reactivation of
memories might lead to a surge of sleep spindles in a sleeping person's
brain. To find out, they devised an experiment in which people learned to
associate particular adjectives with particular objects and scenes. Some
study participants then took a 90-minute nap after their study session,
whereas others stayed awake. While people napped, the researchers cued
those associative memories and unfamiliar adjectives. As expected, the
researchers saw that memory cues led to an increase in sleep spindles.
Interestingly, the EEG patterns during spindles enabled the researchers to
discern what types of memories -- objects or scenes -- were being
processed. The findings add to evidence for an important
information-processing role of sleep spindles in the service of memory
consolidation, the researchers say.
Dreams subconscious links to the
When dreaming you don't have the same awareness as when you are
conscious and awake. When dreaming you also don't have access to
all your memories and knowledge
like you do when you are
conscious and fully awake and alert. This is why some dreams
don't make sense. You say and do things in your dreams that you
normally wouldn't do. Now why would our brains do this? It's not
a fair test of our knowledge. So maybe it's your brain just
saying hey "what if?" The brain never stops thinking, which is
good. But when you're sleeping and dreaming, how does the brain
decide what to think about? And how does the brain know if you
are even paying attention to the dream? I know when I am working
on something that requires many hours of thinking and doing, my
dreams sometimes are focused around those actions and thoughts.
Like when actors are studying the characters they are going to
portray in a movie, they spend many hours transforming
themselves to become this character, thus some have said that
they had dreams relating to this focus of attention. I believe
that when the sub-conscious mind is more linked to the conscious
mind, what ever you are learning, this becomes more focused and
more clearer. Like the
10,000 hour rule
. The sub-conscious mind becomes more linked
to the conscious mind, thus you become an expert or a
professional in the craft that you are studying. If this is the
case, then the subject that you're studying should be important
to increasing understanding yourself and the world around you.
So you become more strong minded and much wiser then the day

professional thief who steals information by infiltrating the subconscious
minds of people during sleep.
"It would be cool if our memory recorded
every dream that we ever had, and organized them so you could
easily recall any dream and play it back. But for now I can only
remember the dreams that I was aware of having, and even those
begin to fade over time. Maybe we need to build a Google glass
for inside the brain?"
"Some people think that when sleeping on
their right side they have mellower dreams, with themes of
relief, joy, peace and love. They also report feeling better
rested and less dysfunctional during waking hours. Sleeping
exclusively on the left side can put pressure on the organs on
that side of the body, like the stomach and lungs, that is why
some left-side-sleepers are more likely to have nightmares."
"I like going to bed around 9-10 pm so I
can get up around 5-6 am
and start my day feeling rested and
ready to go. Not sleeping good really sucks, it's mentally and
physically draining. that is sleep depravation is used as a
method of torture, because not sleeping is freaking brutal.
Imagine always having a hangover, life would suck. Enjoying the
work that you do helps you sleep, Enjoying the work you do also
makes getting up early really a lot easier. Having something to
look forward too the next day is great, but I don't get too
excited, because then it will effect my sleep, which has
happened many times."
Analyzing Dreams - Meanings of Dreams - Dream Interpretation
- Dream Evaluations - Dream Symbols
I would be very carful when trying to Interpret your dreams for
meaning. Even though your dreams may indicate some underlying
issue or fears that you may have, you should always proceed with
caution because you may misinterpret your dream which could
cause you to make adjustments in your life that may or may not
have the desired effects that you were looking for.
It's a good idea to write down the dreams you have because it
will always make them easier to analyze later. Approximately 50%
of a dreams details fade rather quickly after waking, so if you
don't write them down early you will remember less details of
that dream as time goes by.
is the process of assigning meaning to
dreams. In many ancient societies, such as those of Egypt and Greece,
dreaming was considered a supernatural communication or a means of divine
intervention, whose message could be unravelled by people with certain
Psychoanalytic Dream Interpretation
is the process of
explaining the meaning of the way the unconscious thoughts and emotions
are processed in the mind during sleep.
Maybe dreams are just
for the information that's being processed by the
brain, like a form of interpretation. If this is true, then this
would add a whole new dimension to analyzing our dreams.
What if learning to control some of our dreams gave us some kind
of benefit? Like over coming fears or understanding and
controlling our behaviors.
"Some of my best ideas and thoughts come
to me during that time when I'm not totally asleep
, and not I'm
totally awake either, that place in between. That is where I
have had some of my most interesting ideas happen. In that calm
state of mind. It seems that the Brain never stops thinking,
especially in the moments right before you sleep and in the
moments right after come out of sleep. And your brain doesn't
wait for you to be totally aware of your thoughts either. But
because your memory is always working too, when you finally do
become aware that you are awake, most of the time you will be
able to recall what you were thinking about, and also, what you
were dreaming about. So the brain can think on its own, and
luckily, the brain can
remember own its own
too. What a beautiful machine."
"Our brains are wired to keep ticking along in thought--sorting
information and generating possibilities, practical and
impractible.--through our every waking moment. When we have
nothing else on our minds, this helps maximize the use of brain
power that would otherwise be wasted." (Jerome Singer Ph.d)

washing away harmful waste proteins that build up between brain cells

Does not remembering a dream change the way the brain stores
that information from that dream? What happens to the
dreams that we don't remember? I know I had a dream but I just
can't remember the details of that dream. Is it important?
Maybe our dreams are giving us a glimpse of how our brains
process information? It's like your subconscious mind is saying
"If you don't start defining what you're seeing in the world I'm
going to just keep making stuff up", ok, ok, don't get so bossy.

Dreams can change seamlessly from
scene to scene from one place to the next
, so they are always
surprising. Even people and things change seamlessly, changing
from one thing or one person to another,
change sometimes too, but not every dream is

whole other world that you live when you sleep. Dreams also have a diminished awareness,

smell, are virtually absent. Which is the opposite for blind

Father, the Sleeper has Awaken
Birds who can Sleep while
have been observed sleeping in mid-flight, so there is
evidence that birds do indeed sleep while flying
would exhibit unihemispheric slow wave sleep (USWS), a
phenomenon in which animals sleep with only one hemisphere of the brain at
a time, allowing them to keep one eye open
to watch out for potential threats. Frigatebirds are able to fly with both
of their eyes closed. The monitored birds even experienced brief bouts of
rapid eye movement (REM) sleep, although they lasted only a few seconds.
During REM sleep, muscle tone is reduced, causing birds' heads to droop.
Despite this muscle tone reduction, REM sleep was not found to affect the
birds' flight patterns. Though the
did sleep for brief periods of time in mid-flight, they
spent a majority of the flight awake. On land, frigatebirds can sleep for
over 12 hours in a single day. While flying, however, they spent less than
3% of their time asleep, sleeping about 42 minutes per day on average.
Mid-flight sleeping also occurred almost exclusively at night even though
frigatebirds on land can sleep during the daytime. Dolphins have also been
observed exhibiting USWS, allowing them to sleep while they are still
Unihemispheric Slow-Wave Sleep
is sleep with one half of the brain
while the other half remains alert. This is in contrast to normal sleep
where both eyes are shut and both halves of the brain show reduced
consciousness. In USWS, also known as asymmetric slow-wave sleep, one half
of the brain is in deep sleep, a form of non-rapid eye movement sleep and
the eye corresponding to this half is closed while the other eye remains
open. When examined by low voltage electroencephalography (EEG), the
characteristic slow-wave sleep tracings are seen from one side while the
other side shows a characteristic tracing of wakefulness. The phenomenon
has been observed in a number of terrestrial, aquatic and avian species.
