This isn't the first time I've had a dream with someone I know in it, but they're pretty rare for me and something about this one has been bugging me. Any ideas on interpreting it would be really appreciated!

I'm 19 and I've just started university, so I've been living in a new town for a couple of months now.
I dreamt that my friend in the second year had hold of my socks, for some reason (they were black). I can't remember if I gave them to him or he stole them, but it didn't really concern me at the time. However, he put them in the coat pocket of a girl on my course, and she immediately remembered that she was late for something and started to run off.

The thought of losing my socks concerned me a little, so I chased her barefoot across a dream-version of the town I'm living in at the moment, trying to get her attention so I could get my socks back. This seemed to be the main part of the dream, it went on for a long time - I didn't have any trouble running, nor did I feel exhausted. The most difficulty I had was keeping sight of her on the suddenly very crowded high street, and getting past the crowds.

Eventually I caught up with her and she looked in her coat pockets, only to find that she didn't have them and my friend (who I'd left on the other side of town) must still have them. I remember feeling disappointed, then waking up.

I find this hard to admit (probably unreasonably, but hey) since I'd never do anything about it - I have a girlfriend and I love her very much - but I do find the girl in my dream very attractive. I think maybe that's what's bothering me about the dream.
Not sure how any analysis is going to come out ( I dread to think what my socks could symbolise) but I'd really like to know what you think, thanks!
