I've been able to do this, only thing is that if you move to hard you get out of the sleep paralysis, you have to do it carefully little by little, it feels funny too. Its very helpfull when in cases like if your neck starts hurting cause of bad positioning or if your a part of your body gets to cold or hot, I find it more usefull than anything else. but when in to deep stages it just seems to make you enter into the dream already, if your not in it already, or mabey its an OBE, but I couldn't say although its cool cause you feel your body asleep but all of a sudden your standing up without using strenght or anything, the part of my body I mostly feel sleep is my ears, It makes this sound like a tv out of station but harder and it feels like if it is deformed shut, really cool experience, had it a couple of time trying to move late on a wild, strangely after standing I tend to fall back to bed like a log and wake up jumping in rush, you should try it
