I don't have this problem...(not only because I sleep only once a week but because) I wake up suddenly. My eyes come open, and I sit up (then regret doing it*also regret sleeping[but if I don't sleep I hallucinate, and that's not desireable at ALL]*). If only I didn't need any sleep...
(If you think constant and increasing hallucinations is fun, it's not. It's hard to open a door when the knob looks like an eyeball with an upper eyelid, but everything else exposed....and taking a math test over history subjects written in blood really screws your grade.------it's not all bad though. My milk turned into blood, urine, and something else one day, and I didn't drink it for a week. That's when I realized it was actually hurting my stomach quite a lot. I don't have the guts to tell my parents that I'm intolerant to milk, but I found pills about a year later that solve my problem. I now basically carry (those) drugs around almost constantly and am technically doing drugs about twice a day. Normally [I understand] drugs lead to hallucination, not the other way around.)
Anyways, if you know how to not hallucinate and still not sleep that would be helpful.
