Why do humans actually need to sleep

[GraziLovesMary]

hmm interesting, but the only thing i dont really get is how "slowed" down the brain really is..its been awhile since ive had psyc, but i remember something like dreams are created by random synapses firing inside your head, so how "rested" could the brain really be?

Dreaming takes place in REM sleep which comes before and after the deep sleep where restoration takes place. 5 minutes in REM stage can translate to an hour in dream timeline at times. People who dream all night long dont get to enter that deep, restorative sleep.

I actually kind of hypnotize myself with breathing and relaxation techniques to avoid the REM stage entirely. I really only dream when Im drunk or distracted. Or when I want to.
