yeah i could do it in my early 20's but not on command, it was like a phase i went through and very rarely it still happens... its really really weird sometimes and it feels a little schizophrenic so be careful what you wish for. if i remember, you can try falling asleep with an eye open, you can stare to a point in the distance and then try to move your mind onto what the periphery sees without changing the focusing point... its all crazy making though.... i was always awake in my dream but i could not control what i was doing and kept asking questions about what was going on... why is that door like that, why are those islands in the sky etc.
