The jury is still out for me on the literal OOBE interpretation... I"m inclined to think it's all generated in the mind, which is still utterly fantastic....

That being said-

I've had 2 experiences using my Sirius machine where I felt as if I were about to leave my body. It was an intense feeling of it almost happening, or maybe beginning to happen... there was no 'point of reference' in that I was looking down at my body or anything like that, it was more like my center of perception was leaving my body and moving into the visual fields being generated by the Sirius machine. I felt as if I were looking into a huge expansive circular bubble of space, and I was jumping into it. It was great!
