Hypnosis

I know how to hypnotize people.

Seriously. I studied under a hypnotherapist for two years. While I'm not actually a licensed hypnotherapist, I know a lot about the subject.

I know hypnosis is a mystical thing to most people and I know some are interested and curious about it. Some of you may want to use it in your fiction.

So I'd like to know: what questions do you have about hypnosis?
