Troubles du sommeil et cauchemars dans les états de stress post-traumatiques

The repetitive nightmare has been known since antiquity. It is intensely experienced more than contemplated. Although contravening the hedonic principle of the dream, it could have the function of an attempt to master the representation of an event which has not been mastered when it occurred, mainly if some pieces of signification enter it, giving a meaning to the non sense of the trauma. These considerations justify the therapies with cathartic revival under hypnosis or other process.
