dream fragment

I was in a glass cage on the bottom of a hill. Different colored wheels started rolling down the hill, barely missing the glass cage. Behind me was a town full of people who were running my way. They somehow stopped the wheels and got me out of the cage. They started talking to me, but I forgot what they were saying.

Another dream:
I was reading a book on a beach when a lifeguard yelled for everyone to get out of the ocean because of the sharks coming our way. I looked up and saw someone bleeding on their leg with blood all in the water. Everyone looked confused and panicked.
