Derealization

Derealization is a form of dissociation where your surroundings feel unreal, dreamlike, foggy, or visually distorted, even though you know they are real.

Definition

Derealization refers to a sense of detachment from your environment. The world may look flat, colorless, too bright, or as if seen through glass. It often occurs alongside depersonalization during anxiety, exhaustion, or after trauma. Occasional episodes are common; frequent, distressing derealization may warrant clinical assessment.

What it can feel like

  • Familiar places suddenly feel strange or unreal.
  • The world looks like a movie set or through a pane of glass.
  • Sounds seem muffled or distant.
  • People you know feel unfamiliar or two-dimensional.
