I found this today looking for an answer to a question much like yours. It's got a lot of info about alters, but I really liked what it had to say about co consciousness and healthy multiplicity. It gave the "compliant one" in me some comfort.

Just wanted to share.

Alter Identities in Dissociative Identity Disorder (MPD) and DDNOS

It's been a hard night here, with the "h" earphone music kind of night. Compliance did NOT want to deal with it. Tomorrow will be better... It usually is.

Night!
