A friend of mine was facing being homeless and having to go into a shelter if room was available. All options had been exhausted, so I am letting my friend use my spare bedroom on a temporary basis. What I didn't know is that my friend seems to have multiple personalities.
There is the person I knew (albeit not well, but felt well enough to let the person move in). And there is one that seems that doesn't know who I am, throws out random names with no coherent flow from topic to topic. Doesn't feel threatening or confrontational, just more like a random string of names, words, and phrases. There might be a 3rd personality where the person talks about an implant in their face, makes random gestures using their hand from a motion like flicking from the jaw, pointing to the their eye and then flicking from there, and another motion that was similar to a throat slash. That personality seems a little more confrontational.
My question is – what's the best way to deal with this person? Do I bring up the episodes when I think I am talking to the person I knew? Do I try to get a hold of one of their relatives and explain what I am seeing? Totally lost here as this is something I have never directly experienced, although someone I dated about 5 years ago was so hot/cold from day to day that many who knew her wondered if there was more than one personality. It wasn't as obvious as the person I described in the paragraphs above.
