Dissociation Experiences

Dissociation
A disruption or discontinuity in the normal integration of consciousness, memory, identity, emotion, perception, body representation, motor control, and behavior.
Depersonalization
The feeling of being detached from one’s own body, mind, or sense of self (e.g., feeling like an outside observer, numb limbs, or disconnected from one’s reflection).
Derealization
The feeling that one’s surroundings are unreal, dreamlike, foggy, artificial, or distant.
Dissociative Amnesia
Inability to recall important personal information, usually of a traumatic or stressful nature, that goes beyond ordinary forgetfulness.
Dissociative Fugue
Reversible amnesia where a person unexpectedly travels away from home or work and may adopt a new identity or experience confusion about their primary identity.
Autoscopy
Experiencing oneself as being outside one’s physical body while seeing oneself from that external perspective.
Somatoform Dissociation
Dissociative manifestations expressed physically in the body (e.g., unexplained non-epileptic seizures, sudden blindness, motor paralysis, or severe pain without physical cause).
Intrusive Recall / Flashbacks
Re-experiencing traumatic events involuntarily. Ranges from visual memory fragments to somatic (body) flashbacks where physical sensations recur, and can be visual, auditory, somatic, or emotional.
Trigger
An internal or external stimulus (sound, sight, memory, sensory input) that brings up intense trauma memories, emotional responses, or involuntary dissociation.
Trance State
A temporary alteration in consciousness characterized by unresponsiveness to environmental stimuli and focused internal absorption.
Time Loss
Missing minutes, hours, or longer stretches of time when another part or alter was in control of executive functioning.
