I'm really surprised so many people listed Extraordinary Proof actually... The method's been done before, with MUCH better presentation and justification.
Actually it has a great presentation that you can connect with your spectator with! I did this with a very spiritual person and talked about deja vu, and re-occurring dreams, and talked about the movie 23 for a while. She got very into the conversation.She started tearing up at the end of the effect because she was so into what I was talking about.
You missed the point completely. I'm not saying it can't turn into a good effect, I'm just saying that there's much better out there, that start off better than what is offered here.
