Altered perception including loss of the sense of one’s own reality
Explanation:
Depersonalization is the phenomena where an individual feels detached from their own body. They lose the sense of reality and cant figure out their feelings or senses. They often separate their mind and body in a way where they view their own self as an outsider.
It can be experienced by anyone suffering from anxiety or stress but is chronic in some people who have faced a serious trauma. It is a classic symptom of dissociative disorders like dissociative identity disorder. Sometimes it can also be observed in people suffering from non dissociative disorders like bipolar, borderline personality disorder, schizophrenia etc.
