Dissociation

Dissociation is a disconnection between aspects of experience that would normally be integrated: thoughts, feelings, sensations, memory, identity, and perception of the world around you. It exists on a spectrum, from the brief and unremarkable to the complex and significantly disruptive.

At the milder end, most people have experienced momentary dissociation, arriving somewhere without registering the journey, losing track of time, or feeling briefly unreal after a shock. These experiences are common and usually unremarkable. At the more significant end, dissociation can involve persistent disconnection from the body or self, sustained gaps in memory, profound uncertainty about identity, or the experience of distinct internal states that feel separate from one another.

Dissociation is not a sign of weakness or instability. It is a protective response, developed by a nervous system that needed to manage what couldn’t be processed or escaped at the time. Understanding it as adaptive rather than pathological is usually where the work of healing begins.

Why Dissociation Develops

Dissociation most commonly develops in response to trauma, particularly chronic relational trauma that begins in childhood. When a child’s environment is consistently frightening, unpredictable, or emotionally unavailable, the mind learns to create distance from experience as a means of survival. That capacity doesn’t simply resolve when circumstances change. It becomes a learned response pattern, often operating automatically and outside conscious awareness in adulthood.

The Dissociative Spectrum

Depersonalisation involves a felt disconnection from the self. You may feel detached from your own body, emotions, or thoughts, as though observing yourself from outside rather than inhabiting yourself from within. The body may feel unfamiliar or unreal. Emotions may be registered intellectually without being felt.

Derealisation describes a sense that the external world is unreal, distant, or distorted. Familiar environments may feel strange. Colours, shapes, or sizes may appear altered. There may be a felt sense of glass or distance between yourself and everything around you. Depersonalisation and derealisation frequently occur together.

Dissociative Amnesia involves gaps in memory that go beyond ordinary forgetting. This may include missing periods of time, an inability to recall significant personal information, or finding evidence of actions or conversations with no recollection of them. The gaps tend to cluster around emotionally significant material.

Dissociative Fugue is a form of dissociative amnesia involving purposeful travel or confused wandering, combined with amnesia for the episode and sometimes for aspects of personal identity. A person in a fugue state may leave their usual environment, travel to unfamiliar places, and have little or no memory of doing so. Fugue states are relatively rare and are usually associated with severe or prolonged trauma. They warrant specialist clinical assessment and support.

Identity Confusion describes persistent uncertainty about who you are, a difficulty accessing a stable or coherent sense of self, preferences, values, or personality. It can feel as though your sense of self is shifting or out of reach rather than settled.

Identity Alteration involves noticing distinct shifts between different ways of being, feeling, or relating, sometimes experienced as different versions of yourself that emerge in different contexts. At the more significant end this shades into the presentation described below.

Dissociative Disorders

The DSM-5 identifies several dissociative disorders, each representing a different point on the spectrum.

Dissociative Identity Disorder (DID), formerly called multiple personality disorder, is characterised by two or more distinct identity states that recurrently influence behaviour, often accompanied by significant gaps in memory for everyday events or traumatic experiences. DID develops in response to severe and usually early relational trauma and represents the most organised form of structural dissociation. It is more common than is often assumed and significantly more misrepresented in popular culture than any other dissociative presentation. People with DID are not dangerous. They are, in most cases, highly functioning adults who developed an extraordinarily effective means of surviving unbearable early experience.

Other Specified Dissociative Disorder (OSDD) covers presentations with significant dissociative symptoms that don’t fully meet criteria for DID, including identity disturbance without fully distinct alternate identity states, or chronic dissociative symptoms following prolonged trauma. OSDD is a common and clinically significant presentation that deserves the same specialist attention as DID.

Depersonalisation/Derealisation Disorder is diagnosed when depersonalisation or derealisation are persistent and cause significant distress or impairment, while the person retains insight that the experience is subjective rather than reflecting external reality.

Unspecified Dissociative Disorder covers presentations that cause significant distress or impairment but don’t fit neatly into the categories above, including trance states and acute dissociative reactions to identifiable stressors.

A Note on the Word “Disorder”

Diagnostic labels can imply something is broken or faulty. Dissociation is neither a personal failure nor a flaw. It is a sophisticated adaptation, a set of responses that developed because they were needed, and that deserve to be understood rather than corrected away. Recovery isn’t about eliminating dissociation. It’s about developing enough safety and internal connection that the system no longer needs to work so hard.

How I Work With Dissociation

My work with dissociation is rooted in relational psychodynamic therapy, informed by attachment theory and the Theory of Structural Dissociation. I work with adults across the full dissociative spectrum, including mild to moderate dissociative presentations, complex dissociative disorders, OSDD, and DID.

I don’t push through dissociative states or try to override them. I work with them, treating each response as meaningful and paying attention to what it’s protecting. The pace of the work is determined by what the nervous system can tolerate, and the therapeutic relationship is central to the process.

I also offer clinical supervision to therapists working with dissociative clients, including those encountering complex presentations for the first time. If you’re a clinician looking for specialist supervision in this area, please get in touch.

If you recognise yourself in any of the experiences described here and would like to explore whether therapy might help, I’d be glad to have an initial conversation. Get in touch at samanthamerry.co.uk/contacts.
