I've read a ton of books on the subject, that was quite a few years ago so I don't know what to recommend.  I had quite an experience that has stayed with me ever since that's too long to talk about here, but it was convincing enough, and I'm not prone to falling for supernatural explanations to explain what I don't understand.\n\nIn a nutshell, you need to be very relaxed and not in a place you can be distracted.  A breathing excercise helps, I use the "breath in to count of three, hold for four, breath out for 5" routine.  Get as relaxed as possible and concentrate on raising yourself up out of your body.  If you can concentrate easily it takes less tries of course, but you will actually feel it happen.  Whether that's a dream or not I don't know.  When you get to that point pick a place in the house to go to and concentrate on going there.  It's really simple, and doesn't take a great deal of effort.  This is the stage I was able to achieve, around 1986, when I stopped and never did it again.  Nothing really scary, I guess it just convinced me enough and I left it at that.\n\nGood luck.
Does anybody know how to Astral Project? (controled out of body experience)?
