Have you ever paid for the services of a psychic or palm reading? There are a number of shops in the area and near where I live and they must have a good size customer base or they wouldn't still be open. How many people really dig this kind of thing? I know of one person in my life that does, but she actually believe's she can see ghosts too. In my opinion, these are just things they lead themselves to believe in their own brain and is not really reality.
