Meh. Don't ask why or what reason or anything, but in the past I had serious insomnia, not the normal "oh i don't sleep :much:" those are people with very quick rem-cycles. I mean i didn't sleep for about 2 and a half months. You do begin auditory hallucinations, paranoia, and everything seems like a lucid dream, and require pretty heavy medical help, they'll give youthings to make you sleep chemically although they can't force you to take them, the best sleep :is: natural sleep. They also refer you to a psychologist and a psychiatrist almost instantly when you pass the 3 week line, "or at least that's what i was told".
Oddly enough i :am: one of those people who doesn't require much sleep naturally, "my rem cycle is about 35 minutes" I only need about 3 hours for a full recharge, but if i'm bored or have nothing to do i can manage to stay asleep for as much as 13. "i wake up every 3 hours though".
