In Dissociative Identity Disorder (DID), formerly known as Multiple Personality Disorder, an individual may have different identities or personalities known as "alters." These alters can have their own thoughts, feelings, memories, and behaviors, and they may take turns controlling the person's body and consciousness, known as switching.
While one alter is in control ("fronting"), the other alters typically reside in the person's mind. It's essential to understand that the mind in this context is not a physical space, but a way to conceptualize the various identities within the person. When an alter is not in control of the body, they may be in a state of "dissociation," which can vary in intensity.
Regarding sleep, there isn't a collective physical brain space where the alters sleep while not in control. When an alter is not fronting, they may be in a state of relative dormancy or dissociation. During this time, they may not be actively engaging with the external world, and their awareness of the passage of time may vary. Some alters may be more aware of the experiences and activities of others within the system, while others may have limited awareness or memory of what happens when they are not fronting.
It's crucial to recognize that DID is a complex and often misunderstood disorder. The experiences of individuals with DID can differ significantly, and not all aspects of the condition are fully understood by researchers or mental health professionals. Additionally, the portrayal of DID in popular media may not accurately represent the reality of the disorder.
If you or someone you know is experiencing symptoms or concerns related to dissociation, memory gaps, or identity issues, it's important to seek professional help from a qualified mental health practitioner who is experienced in working with dissociative disorders. They can provide a comprehensive assessment and appropriate support or treatment.
