Rukya, that's happened to me, too. Freezing or dropping me from the room repeatedly, and like Miss Brandy I find I'm chatting with meself.
I've found that restarting my entire system seems to remedy that. Although, by the time I get back on it's too late and the person (especially if it's the first time rooming with them) thinks I'm a creep and will not reply to an apology.
It can be frustrating, because as a guy we usually only get ONE chance.
