All I can say is Wow! don't know how to help but know that you were heard. Sounds very bizarre indeed! But then, the whole DID thing is still very bizarre to me...and i guess that in my journey, if I've learned nothing else, I've learned that
anything is possible!
I would have done what you have done and broken contact with that person. Protection of the self is paramount, so feel safe any way you need to.
Good luck!
