By Mayo Clinic staffDepersonalization is a sense that things around you aren't real, or the feeling that you're observing yourself from outside your body. Feelings of depersonalization can be very disturbing and may feel like you're losing your grip on reality or living in a dream. Many people have a passing experience of depersonalization at some point. But when feelings of depersonalization keep occurring, or never completely go away, it's considered depersonalization disorder. Depersonalization disorder can be severe and may interfere with relationships, work and other daily activities.
