dream about a classmate

there's this girl that sits behind me in one of my lectures that I had a minicrush on at the beginning of the semester, but then I fount out she had a bf so it fizzled pretty quick. We talk here and there before or after class, but it's usually about schoolwork or something. anyways here's the dream:

I am talking to her through a instant message thing through myspace or facebook or something(I'm not on either) and I told her on there I would like to take her out and give her a good f--king(which I'm way too shy to ever actually say that, even in a joking way). she replies back that she might have to take me up on that because she's not happy with her bf. after that, it seems that I am not getting all the messages because they aren't making sense, then the im window won't let me scroll up to see the beginning of the message and she asks why I keep logging on and off. so I try to ask her if she has aim or yahoo im but I never see the response, so I don't know if she has it or not and I ask again and still don't see a response. then my brother and mom come in so I have to get off the computer and have to stop talking to her, and then I try get on later and she's not online.

So can anyone interpret this?
