Ok, just last night, I had a incredibly strange dream involving the Joker from Batman (I think) and a girl i know and really like. Well, a few weeks ago, this same girl and i had a 1-day relationship and split because she thought we had a different type of relationship.

Now, in my dream, I met up with her at some point about midway through the dream. She asked me to hold her and I did. We then began to walk hand in hand to some location and she stated, if i remember right, that she had another crush on me and did want to be together with me (or something along those lines, i cant remember this part well). When we got the destination, some kind of theater or place with many seats, I pulled her up on my lap and we sat there; I also kissed her on the cheek not long after sitting. After this, I don't remember a whole lot about the rest of the dream.

Does this mean anything?

I think this dream is about your wishing that she does want to be with you. A theater is a place where you see performances of stories that aren't real, so being in the theater could be your unconscious' way of reminding you that it's all just a wish/fantasy, and you shouldn't get your hopes up.

The Joker could also be a message that it's all a big "joke" - not real.
