People usually associate multiple personality disorders, or dissociative identity disorders, with something more bizarre, like having an adult slip into the mind of a five year old. In a similar case, can it be argued that addictions, and behaviors that appear "out-of-control", be symptoms of multiple personality disorder? An individual might appear fine in the beginning, and they do everything they need doing, yet be out-of-control with normal day operations a few months later. Behaviors that interfere with normal day operations can appear simple, like spending too much time online (internet addiction), gaming (game addiction), eating (food addiction), or more serious like alcohol or drug abuse. The reason for declaring these behaviors that of a dissociative identity, is because the person appears to lack control over what they are doing; it is almost like they are following an instruction. Multiple "personalities" have been linked to mental abuse, which forces the person to assume another identity, so as to protect the original.
If addictive behaviors are self-harming, and stem from lack of control from the individual due to past trauma, would that be one aspect of a dissociative identity? What are your opinions? Thank you.
This idea has occurred to me while reading the book A Course in Miracles, in which it talks about the "created self" ("ego"), and the "true self" ("Holy Spirit").
