>What is this experiment to prove I'm not lucid dreaming?

For decades magician and debunker of supernatural claims James Randi placed a new object on his dining table every month, and offered a million dollar prize to anyone who could tell him what the current object was. Of course the prize was never claimed.

Ask a friend down your block to put something on their dining table. Do your OBE thing and write down what you saw. If you're right you'll have proven you're not lucid dreaming and be world famous for demonstrating the reality of psychic phenomena.
