Dissociation can be defined as disruptions in aspects of consciousness, identity, memory, physical actions and/or the environment. When a person experiences severe dissociation symptoms, they may be diagnosed with a dissociative disorder. The specific signs and symptoms of dissociation for any given person vary depending on the type of dissociative disorder they experience (list of dissociative disorders). When dissociation symptoms become severe, they can disrupt daily life.

Symptoms:
• A major inability to remember personally-relevant events in a way that can’t be accounted for by regular forgetfulness or a medical condition (amnesia)
• Confused and dazed wandering (known as a dissociative fugue)
• Two or more identities or personality traits within a single person
• Transfer of behavioral control to each identity
• Feelings that objects in the external world are changing in shape and size
• Feeling that people are automated and inhuman

Signs of dissociation:
• Mental health problems such as depression, anxiety and suicidal thoughts and actions
• A sense of detachment from oneself; seeing one’s life as if it is a movie
• An unclear sense of identity
• Significant stress or problems in relationships, work or other important areas of your life
• A presence of multiple people talking or living in your head, or a feeling of possession by another identity
