Under the right circumstances, you might do those same things without being hypnotized. It is unlikely you would do under hypnosis anything you would not do otherwise. This issue is in dispute. When hypnotized subjects are left alone, they usually maintain the condition induced by their hypnosis. Hypnosis can be used to create hallucinations in the hypnotized subject.
Hallucinations are perceptual experiences that occur without sensory input.
Some hallucinations are said to be positive when a person perceives something that is not there. When asked, the person reported feeling little pain, just as expected. The hypnotic suggestion was working. No, probably not, although there is no more hotly contested issue related to hypnosis. I might be able to convince you under hypnosis that you'd better remember your psychology and lead you to want to remember your psychology, but there is no evidence that hypnotic suggestion can directly improve your ability to learn and remember new material.
