i have a friend that always talks about his experiences. He's actually the one who introduced me to the idea. before that i had no idea this was even possible. but anyway, my point is, he's only 19, and he claims to have had many experiences with astral projecion.
also, i dont know if this is true or not but i read somewhere that habitual users of recreational/psychedelic drugs can achieve conscious astral projection easier. My friend i speak of, in fact does use psychedelics often, so that could be why.?. actually he said the first time he ever experienced it was while he was on mescaline... so there you have it, drugs can be beneficial
