No, a person with Dissociative Identity Disorder (DID) cannot be in two different bodies at once. DID, formerly known as multiple personality disorder, is a dissociative disorder characterized by the presence of two or more distinct personality states, also known as alters or dissociative identities, within the same individual.
While each alter may have its own unique characteristics, memories, and behaviors, they all reside within the same physical body. These alters can take control of the person's behavior and thoughts at different times, leading to gaps in memory and a sense of detachment from oneself, but they do not inhabit separate physical bodies.
The phenomenon of "being in two different bodies at once" is not consistent with the understanding of DID or supported by scientific evidence. The dissociative experiences in DID occur within the same individual's mind, involving different aspects of their identity, but not separate physical bodies.
