Dream About Escaping Prison With Undead Survival

This dream was about

Several people and myself were locked inside of a prison-like facility with a large population of undead. We were kept seperate from the dead people unless the guards decided to put a few in the same area as us. I managed to escape with a bag and one other person, before being caught I managed to hide money I had in my bag somewhere else. The guards then attempted to lock me and a second person in a yard with dead people, but we managed to survive.
