What does my dream mean?

First I was in a city at night, I think I was in a car and as I approached people, I saw that they were looking up at the sky at UFO's. Then there were 2 women who were arrested and were charged with invading the earth and were called terrorists. The women looked normal, not like aliens. I think this bit of my dream was brought up by me last night flicking through the channels and seeing that 'UFO Files' was on. Next I was in maths cl and I was looking at the guy I like and I felt a sudden burst of anger in my dream because he was laughing with a girl but I don't know who she was. Then I was with my friend from my old school and I haven't seen her in real life for about a year and we were in my school, and then it went on fire. I woke up, but it took me ages to get back to sleep because I thought I had really been abducted by aliens. I fell back to sleep and this was the weirdest bit. My dad was Michael Jackson!!!! Except he didn't look like Michael Jackson, just his normal self! He was signing autographs and dancing and I was watching him in concert! I'm not even a fan of Michael Jackson but my mom is. Could anyone explain these weird dreams that I had last night?
