Rat labyrinth

I dreamed we were trapped in a vast labyrinth, crumbling concrete walls of purple, like something out of a dystopian movie, weeds poking up through the soil. The only one who knew the way out was a well-dressed rat, dapper in a dark blue suit. He would occasionally poke his small head through cracks in the wall and windows, as if checking in on our progress. Finally I grabbed him by the throat and pulled him through, choking him with both hands, his face writhing in pain. I demanded he show us the way out, and unwillingly he began to lead the way.
