Different Types of Dissociation

Updated: Jul 20, 2023

What is Dissociation?

Dissociation is a phenomenon that occurs when various elements of an individual’s experience or memory become separated or disconnected from one another. It can range from mild, temporary experiences of feeling detached or removed from reality to more severe and persistent forms that impair daily functioning. Dissociation can manifest in several different forms, including depersonalisation, derealisation, dissociative amnesia, and Dissociative Identity Disorder (DID).



Depersonalisation refers to the experience of feeling detached from one’s own thoughts, emotions, and physical sensations. This can lead to a sense of being an outsider in one’s own body, or feeling like an automaton going through the motions of life. Depersonalisation is often associated with high levels of stress or anxiety, but can also occur in response to traumatic events.


Derealisation is similar to depersonalisation but involves a disconnection from the external world, leading to a sense of unreality or detachment from the environment. People may feel as though they are observing the world from a distance, or that their surroundings have become unfamiliar or dream-like.

Dissociative Amnesia

Amnesia refers to the inability to recall important information or experiences. Dissociative amnesia is a type of amnesia that is not due to a physical injury or substance abuse, but is instead caused by psychological distress. This can take the form of gaps in memory for specific events or periods of time, or the complete inability to recall important information about one’s life.

Dissociative Identity Disorder (DID)

DID, previously known as Multiple Personality Disorder, is a severe form of dissociation that involves the presence of two or more distinct personality states. These personalities, or alters, have their own unique thoughts, feelings, and memories, and can switch control of the person’s behavior and consciousness. DID is often associated with a history of severe childhood trauma, and individuals with the disorder may have difficulty integrating their experiences and memories into a coherent sense of self.

It is important to note that dissociation is a complex and multifaceted phenomenon that can manifest in different ways and to varying degrees in different individuals. The types of dissociation described above are not mutually exclusive and can occur together or separately. Additionally, the experience of dissociation is unique to each individual and can be influenced by a variety of factors, including personal history, cultural background, and current life circumstances.

In conclusion, dissociation can take many forms, from mild, temporary experiences to severe and persistent symptoms that impair daily functioning. Understanding the different types of dissociation can help individuals seek appropriate support and treatment, and can inform future research into the underlying causes and mechanisms of this fascinating and complex phenomenon.
