A Dream

I dreamed last night:

I was standing in a crowd on the side of a street. The street and traffic lights are made of stone. I know that it was the enemy that did it. They touch things and turn them to stone. They stay to the streets though. The enemy is similar to a metal block, I just took it for granted that they can move at a regular speed, though the specifics of their propulsion eludes me. They were transporting their wounded, small square piles of stone and dust, to a abandoned brick factory at the edge of town to repair them. One of the people on the other side of the road steps through them towards our side. He is a prominent politician, becoming a statue in the middle of the road.
