I agree with Amos as far as getting an adult to things that go against his nature. You might find this article interesting.

Although it's been many years ago now, I have actually hypnotized people. As adolescents my brother and I were fascenated by The Search for Bridey Murphy and the possibility of “remembering” previous lives. We read everything we could find at the library and practiced until we could hypnotize friends in the neighborhood. We would then leave post-hypnotic suggestions designed to let us reinstate the trance state quickly any time we choose. It was amusing to leave innocent post-hypnotic suggestions and then watch the perplexed expression on a subject's face as, after awakening, he performed some action for which he had no conscious motive whatever.

This activity was an extremely bad idea. I'm ashamed to say that our little stunt produced some psycological harm in at least one of our “subjects” and I wish we'd never tried it. I have never tried it again nor will I. I think hypnotism should be left to carefully trained medical professionals.

I should add that we never tried to get a “subject” to do anything dangerous, immoral or illegal. We understood the potential for harm and had no desire to embarrass or harm anyone.
