The way I've understood the classifications of alters...they can just be urges, irrational over extended pressures- I too get them.

Dissociative memories don't have to be full blown Others....they are like seperate memory pockets that exist on their own battery, so to speak. They may not talk or be,... But they are still there, fragmented from the rest and running on their own juice. They are still a part of you seperated and clinging on.

They may not verbally communicate, but they still exude feelings, emotions, preservation, they are still scared and need to be brought back in for comfort or they will forever react the only way they know how because of the trauma.

I really wish you and them luck.
