I think it's like all these "mind readers" there are enough people who know enough about extracting just enough info, or know you well enough, or are very clever at drawing information out of you without realising and making this work to make it look supernatural. Don't get me wrong there's a lot of skill involved just like that Derren Brown guy. I just don't believe in magic and that sort of thing. I'm comfortable to believe there are spirits and we have a soul but I don't believe that in this state of conciousness or in this plane of existence we can observer or interact with it. I don't believe that ouija boards or similar things are a gateway into the other world or whatever.
They are fun for freaking people out who need to believe in that sort of thing, or giving people some strength or "answers" or some form of closure I guess. Then again I guess you have to believe it to see it... But I believe you have to be ready to believe it's real to be able to observe it anyway.
It doesn't scare me in the slightest as I think all that is a bunch of rubbish, and I don't believe in all that voodoo, mumbo jumbo. Heck I even walk under ladders and break mirrors to prove the point. Superstition is a waste of time and it's quite pathetic really.
