yes the sum of all alters make up one whole person. here where I live and work the term created means the same thing that you understand...the mind puts up walls between the person that was traumatized and the alters. here where I live and work alters are "created" I dont mean they become out of nothing and added to the system/person with DID...

the brain is an amazing thing. it makes it possible for human beings be "creative" in normal situations this creativity called dissociation allows a person to dream, day dream, space out when bored or under stress, numb their self or even go to the extreme of being creative by shutting off those traumatic events, feelings, memories. (in your words put up walls) around them and what causes them to be triggered.

some where, some time after the person goes through such a chaotic, stressful, triggering....the persons creative brain using the creativity skill of dissociation these walled off parts of memories, feelings events become alternate personalities that have their own jobs, purposes, reasons for being...in essence start interacting with in the internal system of alters and the outside world, just like a human being.

this is how Im using the term created. not to mean the alters just suddenly appeared out of the wild blue yonder to be added.

a person starts out in this world by being one whole person and then through the creative process of dissociation the one whole person is creatively divided into smaller parts called the host and alters.

Im sorry if my language usage is different than yours and may have caused you some upset. I was just using my locations and cultures terms for the dissociative process.
