dream fragment

All I remember is something about people fighting in an arena. That's it.

I remember very little.

1. I got a demo disc that was supposed to have Gears 3 on it, but when I started it the only thing I could play was Skate 2.

2. I was building two giant water slides. One out of ice, the other out of fire. (there's that fire again. I have to realize that fire is obviously a dream sign for me.)

Aug 11-12: I don't remember much. I remember two or three different fragments.
1. I was swimming in crystal blue waters in the ocean worrying that sharks would get me.
2. I realized that I was dreaming and again tried rubbing my hands together. I checked the time in my dream for some reason, even though I already knew I was dreaming. The dream started to fade out so I tried dream spinning, but it still didn't work. I don't think that I can control what I'm doing while I'm trying to get a fully lucid dream, I think its just instinct to rub my hands together. That obviously doesn't work, so I need to try something else. I don't think I ever woke up, I just think it went on to another dream.
3. My room at my dad's house kept getting set on fire. I also remember some witch lady would chant and randomly set stuff on fire. (Why have all my dreams had fire in them lately?)
