ok, here are some examples of what the guy is doing.
Q1) Assume whatever posture you desire. Now you are to think of a name of one of your friends. Think it, don't say it.
A1) The magic guy proceeds to tell you the first letter in the name (correctly) and the last letter in the name (correctly) and then sounds the name out (correctly)
Q2) Two people objects are seated, facing forward, three feet apart from eachother. In one seat we have a girl, in the other seat we have a guy. The magic guy stands in the middle.
A2) The magic guy states to the seated guy, "I am going to poke the girl with my finger. You will feel 5x the poke in the same spot as I poke the girl. (they're both seated, eyes closed.) With his right index finger, he pokes the girl in the side of her gluteus maximus. The seated guy leaps off his chair in the same direction and grips his right buttock. This is where the girl was poked.
Q3) The magic guy has a seated guy in front of him. He places the seated guy's hand face down on the table in front of him. Seated guy keeps eyes closed.
A3) The magic guy says "When I raise my hand, you will raise your hand. When I lower my hand, you will lower your hand." And the magic guy does several raising and lowering, all matched by the seated guy. Some of the magic guys raisings/lowerings are varied in the wait time with still matching results.
I think I was most likely duped by the card tricks. Afterall, they're tricks.
Now, it looks like he's just pulling people off the beach to do this. Ii sincerely doubt he talked to these people in advance. I don't think it was some "faith-healer" type greasy stuff.
I firmly believe something weird was going on here.
