They stated that people can have dissociated "parts" that are not seperate identities. Just a fragmentation of emotions that one feels but it is still them not a seperate person. They said that this happens in PTSD and Borderline Personality Disorder. It makes sense to me. It explains why I dont hear the chatter other people describe like commentary on daily life stuff like different opinions on what to say do etc. It doesnt explain the random chatter though. Or does it?
