**Dissociative disorders** are a group of [[mental health]] conditions characterised by disruptions in consciousness, memory, identity, or perception. These disruptions can range from mild detachment from immediate surroundings to severe fragmentation of identity. Common forms include: - **Dissociative Amnesia** – inability to recall important personal information, often following trauma. - **Dissociative Identity Disorder (DID)** – the presence of two or more distinct identity states, accompanied by memory gaps. - **Depersonalisation/Derealisation Disorder** – persistent feelings of detachment from oneself (depersonalisation) or from the surrounding world (derealisation). These disorders often emerge as **adaptive responses to extreme stress or trauma**, allowing the mind to distance itself from experiences that are psychologically overwhelming. --- ### **Dissociation and Dreaming** During sleep, particularly **REM (Rapid Eye Movement) sleep**, normal processes of memory consolidation, emotional regulation, and self-representation occur. Individuals with dissociative tendencies may experience **dreams in which boundaries between self and environment are blurred**, or where multiple self-states appear as distinct dream characters. For people with dissociative disorders, dreaming can sometimes mirror waking dissociation: - **Fragmented or surreal narratives** reflecting disrupted self-identity. - **Experiencing oneself from outside the body** or as an observer, akin to depersonalisation. - **Recurring dreams or nightmares** related to past trauma, which may trigger dissociative responses upon waking. Understanding the interplay between dissociation and dreaming helps clinicians and researchers explore how the mind **processes trauma and integrates experiences** during sleep, as well as the broader mechanisms of consciousness. `Concepts:` `Knowledge Base:`
