“Trauma-related structural dissociation should be distinguished from more ubiquitous phenomena that are often termed dissociation, but likely have a different underlying process. Over the past several decades the original meaning of dissociation has been quite extended by the addition of other phenomena not typically considered to be dissociative. These include alterations in consciousness such as absorption, daydreaming, imaginative involvement, altered time sense, trance-like behavior, and “highway hypnosis” (e.g., Bernstein & Putnam, 1986).” Dissociative Identity DisorderDissociationDissociativeDdnosStructural Dissociation Author:Onno van der Hart
