A sense of alienation from normal identity, as though one has become an outside observer with no control of one’s own mental or physical processes.
Example: A woman awakens from a frightening dream and feels strangely unlike her usual self. When she gets up to wash her face, she gets the strange feeling that she is outside of her body, watching herself from the bathroom doorway.
