Funny, seems as though you've made about as much progress in your attempts to prove OBEs as I have! Granted...I only tried a few times a few years ago, and gave up mostly out of frustration and a desire to do more interesting things with my LDs/OBEs than trying to read a playing card.

However, some things have changed...so I might be starting up my own experiment soon...though it will be quite different. I plan to involve other people, because usually I have trouble being convinced of something until another person can verify it. I'll post when I have the details smoothed out.
