I've had one OBE that I can recall - and vividly, at that - but I'm more than certain that I've had them all my life, and just can't remember anything specific about them. The OBE I *can* recall was a vision, and, well... heck; see for yourself.
I've learned that if you try to project, chances are, you'll fail. That's my experience, anyway. If you persue Astral Projection, take it
easy. Don't obsess over it.
