Dreaming of a another me

Think I posted this in the wrong forum before, so here I go in the right one...

Maybe you can help with me with a fractured and somewhat bizarre dream I had last night. It started with me meeting a girl out and about, getting talking to her and making a friend. This part I don't really remember the details of. Later in the dream, I see her coming out of a pub I know in town, but she has bruises on her face. Then she turns and I see the other side of her face and it is fine, she is very pretty. I'm wondering what might have happened to her, if she is ok. She's talking to someone on her mobile phone and I have to go home, I'm near the tram and I'm walking the same way wondering if I should talk to her to find out if she is alright.

I have a vague recollection of doing that, and then I'm somewhere else, perhaps a different dream. I'm somewhere beside the sea, in a building. I can see a beach outside and people on it. I'm with family and friends and another me. I feel no threat, only recognition and a kind of familiar love. This other me is saying things that I would say and behaving the way I would behave, although not exactly the things I'm thinking. I ask other people if they can see this other me and they go quiet. I think it means they can't. Maybe this is what it is like to be schizophrenic, I think. Then I remember the girl and she is there. I wonder if she has drugged me or something like that, so I ask her why the last thing I remember is talking to her and now there are two of me. She doesn't know what I mean, and then the other me continues my questioning and she interacts with it by answering. Baffled, I state that she _can_ see this other me but she does not answer.

What on earth could any of this mean, if anything?
