We should make it a rule not to seek to impose hypnotic treatment on any patient. A prejudice is widespread among the public (actually supported by some eminent, but in this matter inexperienced, physicians) that hypnosis is a dangerous operation. If we sought to impose hypnosis on someone who believed this assertion, we should probably be interrupted, after no more than a few minutes, by disagreeable occurrences, which would arise from the patient's anxiety and his distressing feeling of garded as results of hypnosis.
— Sigmund Freud
