i was kinda wrongish about what i said before........heres how sleep works

you begin sleep by going into stage one (duh) which lasts only a few minutes, and this is where you are jus begining to fall asleep and at this time you can experiences hallucinations, and be awakened easily (like when you suddenly tense up and jerk awake). stage 2 is deeper, but you can still be easily awakened (ie, if someone says your name); sleep talking occurs now. stage three is transitional to stage 4, both of which are long stages of sleep. stage 4 is where bedwetting and sleepwalking occur (mostly from ages 3-12), night terrors are also during stage 4; much more intense than nighmares, night terrors occur in the same age range as the previous. the final sleep stage is REM sleep. the first period is short (10 minutes) but they get longer as you go back and forth between REM and the other stages (after a few times you get to about 45 min or REM). dreaming is during REM sleep, and you are paralyzed during it (this often is sensed during dreams, being unable to move, but not always). REM is when you get recharged, and without it you don't feel rested. arousal occurs for both sexes during REM sleep and is often manifested as "morning wood" for guys.

there is a strong corrolation between the consolidation of memories made during the day (so that they are moved to long term memory, and you really remember them) happening more for people who get more (REM) sleep. ie, you will remember more of what you learn if you get an appropriate amount of sleep that night. i don't remember why (it may not be known) but i do know that naps are superpowerful for recovering sleep debt (explained in my previous post) as you experience more REM sleep.

i had to look up some of this stuff on my psych teachers site (http://yhspatriot.yorktown.arlington.k12.va.us/~wwheeler/newbies.html) if you like psycholgy, check it out!
