Multiple Personality Disorder or Dissociative Identity disorder 
Dissociative Identity disorder is a common psychological disorder in which a person shows attributes of many people, that is there are multiple and distinct personalities that exist within one person. These personalities react and act with the surroundings. The whole phenomenon is like watching a movie, relating to the character of the movie and going through all the situations that he goes through but at no point of time do we forget our own identity but then there are some people who fail to do that. They assume the identity of the other character and thus release their suppressed feelings and emotions in this kind of a mitigated way.

One personality is absolutely oblivious of the other one’s presence but both the personalities take control of the individual at regular intervals but then there is no shared memory. The most interesting characteristic of this disorder is that the alternate personality is an individual in it and has its own history and array of experiences. Gender and voice also changes, at times the alternate personality shows features like weak eyesight. Isn’t it surprising that two personalities exist in the same body and manipulate the body as per their requirements and all this is facilitated by the power of human brain? Initially this disorder was also known as "Multiple Personality disorder".

Signs and Symptoms 

Some of the signs and symptoms that show in case of Dissociative Identity Disorder are similar to that of any physical disorder like the following:

• Mood swings
• Abnormal fears
• Suicidal tendencies
• Depression
• Sleep Disorders
• Alcohol
• Partial loss of memory like forgetting certain incidents and occurrences

The other symptoms are a sense of being detached from oneself which is also called depersonalization and there is another phenomenon called derealization that these patients go through wherein the perception of things happening around us weakens and seems to blur.
