Part of the show The Science of Hypnosis
I was hypnotised over 30 years ago and it cost me £5. At the time I was very angry with the hypnotist because I didn't feel like I'd been on another plane at all. The first thing I did when I walked out was have a cigarette! However, after that first cigarette I never had another one again. Hypnosis didn't meet with my expectations but it did seem to work.
To my mind, the hypnotists missed out an important thing at the beginning. It's well worth telling people that hypnosis does not produce odd feelings. People can get up and open their eyes if they wanted. It does not do magical things.
