When I was very young I had a dream I was flushed down in an enormous toilet...
I remember it perfectly

Last night, I dreamed that my home town was this giant kid's toy. This giant asshole kept grabbing me and putting me in promiscuous poses with other people. It made me feel really uncomfortable. I kept escaping and running indoors but the kid would tear the roof off of any house I went into, tear my clothes off, and make me have sex with other un-willing people. And he'd laugh hysterically.

WTF?

I have a lot of dream I remember, some even go back to the fourth grade. But two that come to mind whenever someone asks me is:
1 - I was playing in a band show as a drummer, then the band decided to cover The Devil Wears Prada, so that meant I had to switch the back up vocals and rhythm guitar. I didn't know how to play the songs, but no one noticed and we had one hell of a show. I woke up wanting a band more then ever.
2 - Me and a old friend of mine were in the back of a van about to "rock the cazba", it felt so real, and as soon as we were about to start, my roommate knocked on my door and woke me up. I guess in one way it was good he woke me, but I still didn't talk to him for the rest of the day
