Occasionally, the instructions to wake up are not clear to the subject. If this is the case, clearer instructions should be given. You could also deepen the hypnotic state and then give suggestions to awaken at a specific count in a very authoritarian manner. Every so often, I have found that the subject has fallen into a natural sleep and just hasn’t heard the instructions. In this case I raise my voice which is usually sufficient or gently shake the subject awakening him as you would any sleeping person.
I would like to relate a rather interesting experience that I had with a male subject. I had worked with this particular subject six times previous to this occasion. He was a good hypnotic subject, and he failed to awaken in the usual manner. Since he had carried out several posthypnotic suggestions, it was rather perplexing to analyze what had happened. After about ten minutes, he finally agreed while he was under hypnosis to awaken at a given count. I asked him what was the nature of the difficulty. He replied, “I wanted to see how you would react.”
In conclusion, having difficulty in dehypnotizing yourself is extremely rare. Should it happen, _keep calm_, and repeat the suggestions with emphasis. Even in hetero-hypnosis, where the hypnotist hypnotizes a subject, it is extremely rare. There are explainable psychodynamic factors for this. However, they can be met adequately while the subject is under hypnosis.
