I was in a city - I am pretty sure it's Chicago because the book I just finished was set there. It was after some crazy zombie shit went down. Idk what but it was just an established fact in the dream. Zombies had kind of taken over the city but they weren't like Zombieland zombies, they were like World War Z, fast as hell zombies.
I was living in a high rise group apartment place. I had def just moved there in my dream.
The zombies, though, were like T-Rex. They couldn't see you if you were standing still. And they couldn't really hear either. So a group would run past and as long as you were standing still you were fine.
Zombies would take the elevator, too. So you had to be careful if you were trying to get on an elevator - you had to make sure there weren't any on there already.
