Explanation:

Dissociative identity disorder is a serious form of dissociation, a mental phenomenon that results in an inability to connect in the perceptions, memories, emotions, acts or sense of identity of an individual.

It is believed that dissociative identity disorder results from a variety of factors which may include trauma encountered by the disordered individual.

Dissociative identity disorder is defined by the existence of two or more different or split personalities or identities of personality which have continuous power over the actions of the individual. The "alters" or other characteristics have their very own age, gender, or ethnicity.

Each one of them has their own poses, movements and distinctive ways of speaking. The alters are sometimes fictional people; sometimes they can be animals. It is called "switching," as each personality shows itself and influences the actions and thoughts of the individuals.
