John Edward uses the Wizard's First Rule from Terry Goodkind!
But in all honesty, when it comes to that 'Crossing Over' ghost sort of thing, I was at a lecture/presentation about a decade ago that was given by Ed and Lorraine Warren (ghost hunter type people). Some of the shit that went down in that church (they did it in a church at a local university) made me goddamn glad I was with a bunch of people I knew when I was walking back to my car in the dark. Audio tapes they played of an exorcism, strange shit going on, things moving, appearing in the corners, shadowy shapes -- sure, it could have all been faked to add to the atmosphere, and I am a pretty skeptical bastard but I came out of there scared to death.
The worst part of it was, after all this weird shit went down, my crew went up to meet them and Mrs. Warren started asking us really personal questions about stuff there is no way they could have known about, since we were just random people who showed up for a presentation using tickets we weren't supposed to have (we didn't go to that school, but we pulled some strings to get it.

). Asked my buddy about a leg injury he suffered while playing Lacrosse a year prior (the guy was a track runner who got hurt goofing off in a lacrosse game), asked me about how I was dealing with some personal shit in my life.
Its not like we asked her to give us a reading, we just wanted to shake their hands and comment on the presentation, and then she busts out with, 'how's the leg coming along from that lacrosse incident' and 'chris, how are you coming along with xxx?', she said something to my roommate's girlfriend that sent her walking out of that place without saying a word - and trust me, I wish I would have known what because that girl was not one for shutting up at any time.
Some weird, crazy shit -- since that night I think twice when I see shit about people like John Edward, because sure, its 99.9% certain that he isn't REALLY talking to dead people, but man. You just never know for sure.
