I always wonder when I see one of those hypnosis shows, where someone from the audience makes themselves a docile fool in front of a large crowd, whether they are stooges or it is the real deal. But I wouldn't volunteer to get hypnotised to figure that out, in fear of being the next person who stands imitating a dog in heat on such a stage.
There’s a good book about this called Reality is Plastic. It may give you a new perspective.
