What does my dream mean?

I'm going to the sadie hawkin's dance w/ my friend, paul, and i had a dream last night about the dance. so we were at my house before the dance for pictures, and i saw that my friend was there(who isn't evne coming in our group) and i thought it as weird, but that she must've just changed her mind. then, she went over and started talking to paul. they both walked over 2 me and our other friends and said "we're in love now!" i was really upset, but i tried to hide it. then later in the dream, i told my friend that her dress was pretty when i actually thought it was hideous! it was a really weird and awful dream! does anyone out there know what it means?
