For me, it is like can a friend meet us and know that because we all aren't on the same page can they act as like intermediary when we need to escape. For us the scary things is breaking down the potential conflicts having them understand it isn't you but just what you accepted if we are friends....I think it is best to leave it dissociated because it takes a special person to understand that, nobody usually has the time or energy to devote to anything like that usually. I think we prepare because it is new to us to put on new eyes the eyes of understanding . It goes away afters wards just make sure alters aren't so absorded in the therapist agenda .
