Hypnosis doesn't belong on your list with the others. It's actually a therapy involving very deep states of relaxation. And I'm not talking about stage hypnosis where people are made to act stupid for laughs.

As for psychics and the sort, some are real, some aren't. I usually can tell right away when I start asking them specific questions. When I ask the same thing to them all, and I get the same answer, then I know they are for real.
