Your use of the word "systems" seemed interesting to me. I've recently read a book on internal family systems, which is a system within all humans, consisting of the Self and one or more other personalities. This IFS system is a theory that we are not just one personality, but a family of selves that make up our personality. This is separate than the multiple personality theory, from what I understand of IFS.

By using the word "systems", were you referring to the IFS theory or the DID theory? It's possible I'm not using the proper verbiage, here. At any rate, thanks for your thoughts and response.
