Fugue describes a running away without any apparent reasons for outsiders. It is a compulsive running away, because affected people can not control this behavior. This is called an impulse control disorder. The affected person runs away without a goal and follows the escape impulse compulsively, usually disoriented, as can be observed in dementia patients. A dissociative fugue, on the other hand, can be a sign of a multiple personality disorder, often the past is forgotten until the escape, or mentally split off. Usually this is based on a traumatic experience. With hypnosis, the split-off experiences can be gently made accessible to the consciousness again and provide orientation. At the same time, psychotherapy, including hypnotherapy, can help those affected to remember the time when they ran away.
