The lines between registers of interaction (e.g. who you are at work, who you are at home, who you are down the pub), stage personas, and multiple personalities are extremely blurry.

Also "having multiple personalities" is not in and of itself sufficient for a dissociative identity disorder diagnosis.

So you're approaching fractally wrong here in a way that's really quite offensive to a lot of people, and I'm afraid negative reactions are largely going to be inevitable as a result.
