Hypnosis is associated with the treatment of posttraumatic stress disorder (PTSD) for two reasons: (1) the similarity between hypnotic phenomena and the symptoms of PTSD, and (2) the utility of hypnosis as a tool of treatment. Hypnosis provides controlled access to memories that may otherwise be kept out of consciousness. New uses hypnosis in the psychotherapy of PTSD victims involve coupling access to the dissociated traumatic memories with positive restructuring of those memories. Hypnosis can be used to help patients face and bear a traumatic experience by embedding it in a new context, acknowledging helplessness during the event, and yet linking that experience with demoralizing memories such as effort at self-protection, shared affection with friends who were killed, or the ability to control the environment at other times. In this way, hypnosis can be used to provide controlled access to memories that are then placed into a broader perspective.
