Strange Dream

I'm still trying to figure out what, if anything this dream was supposed to mean. Let me break down the elements;

I was in a math class. Math was my worst subject. I hated it. The only times I ever failed in school was a math class of some sort. Perhaps my brain just can't process math.

The teacher was a pretty blond with a nice chest and was practically exposing them to the class. I think any amateur dream reader than crack that code.

Sitting next to me was a girl I knew back in college. We were friends, part of a larger group of friends. I had a thing for her sure, but she had a boyfriend so all we could ever be was friends. We had a lot of adventures together, parties, road trips, etc. One drunken night, I spent the night in her dorm and it was the first time I had ever gone down on a woman. I the graduated and saw her less often. She then got married then I never heard from her again. I ran into her a few years ago at a club with her husband. One thing I never understood was why she, and others in that crowd kept in touch but not with me. I guess that's part of the dream too.
