Dissociation is one of the most misunderstood responses to trauma. You might experience it as spaciness, brain fog, or feeling checked out. You might feel detached from your own body, as if watching yourself from a distance. You might notice gaps in your memory, or feel like the world around you isn't quite real. In more complex forms, you may recognize distinct identity states or personalities inside yourself.

All of these are forms of dissociation — and all of them make sense as responses to overwhelming experience. Dissociation is the nervous system's way of protecting you from what was too much to fully process at the time. It worked. But if it's still happening now, it's getting in the way of your life.

Common forms of dissociation include:

Dissociative Identity Disorder (DID) — the presence of two or more distinct identity states, each with their own characteristics, memories, and behaviors. Formerly known as multiple personality disorder.

Depersonalization — feeling detached from your own body or emotions, as if observing yourself from a distance or living in a dream.

Derealization — a sense of detachment from your surroundings, where the external world feels unreal, distorted, or unfamiliar.

Amnesia — difficulty remembering significant periods of your life or specific events.

Brain fog — a milder form where experiences feel unclear, like looking through a steamed mirror. Present-moment awareness feels hazy or muted.
