Hello everybody, a new persons first post here.
I came in to look at this forum in the hope of finding some scepticism. I was a full-time stage hypnotist for over a decade and, whilst it is true that you can use the technique to get strangers to do unlikely seeming things, the bottom line nowadays agreed by most scientists is that there is no such thing as a state of "hypnosis".
The best single book on the topic is "Hypnosis, Compliance and Belief" by Graham Wagstaff.
I know people who have been hypnotised will contradict me, but so they should: to "be hypnotised" is to fall for the illusion of "hypnosis" just like we fall for the illusion of magic when we see a good card trick.
