What does this dream mean?

I dreamed that I moved to a new school; there was this girl; she had brown flowing hair and freckles and brown eyes. She was mean; she was very religious, and conservative. Most of the people at this school were liberals; no one liked her. Yet everyone would pretend to be like her to get her to like them. I didn't understand why. Some how, I don't remember why, but I was at her house; an ugly little bungalow. Nothing special. At around 8:00 ( I believe it was a Friday night) people started to show up. Then there was music, and dancing and people drinking, smoking pot and doing *unspeakable* things in the bedrooms and the bathrooms. I knew why people hung out with her; she threw great parties; I ne'er really partied; I just sorta hung about. What does this dream mean, if anything?
