Depersonalization (DP) is classified in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) as a dissociative disorder defined as “persistent or recurrent experiences of feeling detached from, and as if one is an outside observer of, one's mental processes or body (e.g. feeling like one is in a dream)” (American Psychiatric Association [APA], 2000, p. 532). DP commonly co-occurs with the phenomena of derealization (DR), defined as “the sense that the external world is strange or unreal” (APA, 2000, p. 530).
