I'm trying to understand what alters are, but it's always confusing. It's a concept that just doesn't belong to the normal human psychology. I cannot find words or terms to describe it without using the DID terminology. But I don't want to use that terminology since it sounds "insane", "not normal" and "incomprehensible" for other people.
I cannot find any other ways to describe it than using their names. The problem is that I have understood that for regular people it is "insane" to use different names for denoting certain parts of your personality (or identity). However, without using their names you need to use long and confusing descriptions. It becomes something like "when I'm in that state where I feel like that and experience myself as this with these memories with barriers to these memories and with this behavior while lacking that behavior etc". That is not a fair description of a certain character, identity or alter. Any emotions may change within a specific alter, so using terms like "Angry Part" is not working. And to simply feel an emotion is not the same as having a certain identity. Besides, how do you describe an 'identity'? Identity consists of a collection of various aspects of a person. Just as a personality consists of more components than a simple emotion or trait.
Also, it is not possible to use simple terms to describe an identity. Is college student an identity? Is sociopath an identity? Is child an identity? Is artist an identity?...Well, in a way they are, but they are very unspecific. A whole identity requires more components than that. Is a "depressed artist" a more accurate description? "Depressed teenage artist?" "Depressed teenage artist with BPD?" Etc...You would always need to build up the description more and more. But what if that specific alter is not depressed today and doesn't care about any artist stuff?...This kind of descriptions would probably sound "insane" too. Especially if I'm neither teenager, artist nor have BPD as a diagnosis.
So, in the end it will always be easier to describe an alter by using the name. But if that concept is abnormal, then maybe there isn't a way. The concept of alters should not be too abnormal. It is based on human psychology (and perhaps even neuroscience). I think there have to be terms and concepts for "regular" people that are using the same mechanisms. Ego states have been proposed to exist in all humans. But even ego states may be incomprehensible for other people, I suspect. Or is that the best way to describe an alter?
How would you think alters could be explained to "regular" people without dissociation? How could it be explained without giving an impression of insanity or evoking stigma?
