What is depersonalisation-derealisation disorder?

'Depersonalisation' means feeling detached from yourself, observing yourself and your feelings and thoughts as if they belong to someone else you are watching in a movie. Some of the typical symptoms are:

  • out-of-body experiences
  • loss of feeling in parts of your body
  • distorted views of your body
  • unable to recognise your image in a mirror
  • a sense of detachment from your emotions
  • feeling like you are watching a movie of yourself
  • feeling like you are unreal

'Derealisation' means seeing other people and the environment around you as dream-like and unreal. Objects may change in shape, size or colour. Typical symptoms are:

  • feeling like a normal environment is unfamiliar
  • a sense that what is happening is unreal
  • feeling detached from the world
  • a perception of objects changing shape, colour, size
  • feeling that people you know are strangers

Youmight experience one or both of these problems if you have been diagnosed with depersonalisation-derealisation disorder, and will probably be aware that these experiences aren't reality.

Episodes of depersonalisation or derealisation may last just a few moments and come and go over many years, or may be ongoing.
