REM sleep lasts about 5-45 minutes, and thats when you dream. Dreams last 5-45 minutes, therefore. An average person with an average sleep cycle gets about 2 hours of REM sleep a night, 2 hours worth of dreaming, usually different dreams for each stage of REM sleep. Sleep paralysis occurs every time we go into REM sleep, but it's only considered a problem when we're conscious of it. From Wikipedia:

"Physiologically, sleep paralysis is closely related to REM atonia, the paralysis that occurs as a natural part of REM (rapid eye movement) sleep. Sleep paralysis occurs either when falling asleep, or when awakening. When it occurs upon falling asleep, the person remains aware while the body shuts down for REM sleep, and it is called hypnagogic or predormital sleep paralysis. When it occurs upon awakening, the person becomes aware before the REM cycle is complete, and it is called hypnopompic or postdormital."

Basically, it happens when one part of you becomes awake and the other part of you is not. However, you are right with one point, that it is still unknown what causes it. It's most commonly linked to stress, but so is cancer, so that really means fuck all.

scientific reason, to perfent actions from your sleep your brain locks your body, sometimes its low and thats why people sleepwalk, or somtimes its too high, in witch you cant move even awaking

The average person has on average thirty-six dreams per night. Although they do not remember them when they wake up, this fact was proven in 1992.


The average person has a major dream every 90 minutes, which is the sleep cycle of a person. There are some medical problems that may make you dreamless, like me, I haven't had a dream in months.

I want to let you know that sometimes you may dream, but you feel like you have had only one dream, that's because you corival cortex may be tired and may not make you aware that you are dreaming, so you may not be alert for some of your dreams. If that happens it is quite normal. And some dreams may feel like you have already woken up.

Yes. Laboratory studies have shown that we experience our most vivid dreams during a type of sleep called Rapid Eye Movement (REM) sleep. During REM sleep the brain is very active, the eyes move back and forth rapidly under the lids, and the large muscles of the body are relaxed. REM sleep occurs every 90 - 100 minutes, 3 to 4 times a night, and lasts longer as the night progresses. The final REM period may last as long as 45 minutes. Less vivid dreams occur at other times during the night.

You have approximately 4 to 6 dreams per night during a stage in sleep called REM (Rapid Eye movement). REM stages and the length of dreams early during sleep can last from 5 to 10 minutes. Stages later during the night can last for half an hour or more.

To try to remember some of your dreams, set a timer to wake you up every 90 minutes. Waking up every 90 minutes will give you a better chance at remembering dreams that would otherwise go forgotten.

There are so many different sites giving me so many different numbers of dreams people have per night that I can be pretty sure when I say that nobody really knows how many dreams that somebody will have per night.

I did some calculations based on hydes numbers. 8 hours being a good nights sleep
8 hours of sleep per night x 60minutes in each hour= 480 480mins/1000dreams per night=.48 .48minutes x 60seconds= 28.80 seconds per dream. Which Hyde more than enough time to kick over a lamp in your fight with the chuck man.

However I'm not going to say if you weren't under the influence of sleep paralysis that you would preform mortal combat with the first lamp you find but i'm not saying you won't either.


This ^ is Exactly thats what I was getting at.

The first yahoo article is completely wrong. There is no known condition on the planet which would make you not have dreams. You may not remember them, but you still have them.

Also, sleepwalking happens at one of the stages of NREM sleep(which takes up the most amount of time), normally at stage 3. Its different from REM sleep, which REM Atonia occurs during.
