I discovered a new type of alter online called a "shell alter" that fascinates me.

A shell alter is an Apparently Normal Part (host alter/front person) which handles daily life and is designed to hide the existence of other alters from the outside world. [10]:33 Shell alters do not exist in DID, they only exist in one form of DDNOS (now renamed to Other Specified Dissociative Disorder). The apparently normal part (ANP) is a shell through whom the inside parts/alters act. The inside parts can come near the surface, temporarily blending with the ANP. The inner parts are not regarded as separate, distinct states although amnesia may exist between them. [7]:9, [9]:5 If DDNOS is caused by ritual abuse and mind control, the shell alter is not supposed to know about the others.[9]:5 Read more: Alter Identities in Dissociative Identity Disorder (MPD) and DDNOS

Does anyone have anything to say about this?

I mean....anyone have direct knowledge of how this works, manifests, does it make you question your sanity?
