I wouldn't call myself a plural system, but I do like to think of myself as a city, or possibly a ship. There are all these people inside me, and I'm not actually any of them directly, but they all have roles and jobs and I like to listen to what they say because they all help me get where I'm going and sometimes they have interesting stories to share.
@Felthry It's a thought, anyway. I don't think I'll know if it applies to me or not unless I see other examples.
