you should read about this form of meditation my friend does(wish i could remember what it's called). didnt believe him at first untill i tried it. you can put yourself in a lucid dream state just by controlling your breathing and going one muscle to another and relaxing them. the first time you do it, it freaks you out cause you literally "fall" into this state and if feels like you are falling off the bed. basicly i went into the dream state and thought i was falling off the bed so i freaked but its tough to slip out of it once you start to enter it. i tried to move my arms but they wouldnt move, making me more freaked but then i started to come around. my hearing started to get louder and i could start to move. then i woke up. i have tried it since but i guess the first time is the easiest then it gets really hard untill you can master/controll it.
