Here's how I not only conquered it, but discovered I could control my dreams as well.
Ive been able to control my dreams for years, its as if my conscious is still working, and im able to think to myself like, ive caught myself couple times "funny as it sounds" freestyling rap in my dreams, couple of my friends would be over, and id be thinking inside my head, and freestylin about excrement around me in that particular moment, its kinda cool considering im sleeping but yet still awake, i cant actually control my dreams, in the sense that i can make excrement appear, or have godly powers, its just as if i was awake, i could run away, i could fight, have sex, or whatever...
but to help me goto sleep, i play my usual games every night, Quake2 Jumps (the real game. not pb) Quake2 Gloom ,Digital Paintball 2 and recently Mirrors Edge.
another game u should check out is Bionic Commando Re-armed, pretty slick.
I also check the forums here, reading and lookin at the photography area is nice to do, i check out rlslog.net every waking moment
getting high b4 u goto bed is easy, and youll fall right into lala land
if u got the next day or or your just part of my family and and get drunk then goto sleep, that's another way to achieve this task.
sometimes i cant goto sleep until i have sex, just gotta get that extra "load" off your back
after all that who wouldn't sleep
p.s. i goto bed around 2am est time every night
