Paranoia - YES and without a doubt I am plagued by it, even to the point where I now avoid people, which I realise isn't healthy but I plan to see people again once I am in therapy and better equipped to deal with it

Dissociation - now with this I am not entirely sure...I will often lose concentration and drift off into my head while watching tele or talking to someone. Sometimes I am listening but then realise I have no idea what they are talking about. The face thing you mentioned, I kinda get that, it's like I am looking at them but their face is almost different in some way but not...it's almost as though I am seeing them but in a different way. I don't know how else to explain it but that's as close as it comes.
