I can tell you that if you were to ask people what is hypnosis in detail, most of them will only give you the few characteristics of hypnosis – trance like, relaxation, heightened awareness, focused attention etc.
Even trained hypnotherapists may not give you a more complete answer. This is because hypnosis is too wide that to contain it within a few characteristics and descriptions is actually shortchanging it.
Perhaps I will come up with a book on the definition, characteristics and concepts of hypnosis in the near future. The book will give a more complete answer (current hypnosis’ understanding by people are limited). When the time comes, I shall disclose it in this blog! Keep a lookout!
