10. Derealization
Derealization (DR) is an alteration in the perception or experience of the external world so that it seems strange or unreal. Other symptoms include feeling as though one’s environment is lacking in spontaneity, emotional colouring and depth. It is a dissociative symptom of many conditions, such as psychiatric and neurological disorders.The detachment of realization can be described as an immaterial substance that separates a person from the outside world, such as a sensory fog, a pane of glass, or a veil. Individuals may complain that what they see lacks vividness and emotional colouring.Familiar places may look alien, bizarre, and surreal. The world as perceived by the individual may feel like it is going through a dolly zoom effect. Such perceptual abnormalities may also extend to the senses of hearing, taste, and smell.
