Dream About Apocalypse Sorcerer Janitor Secret Money Birthday Present

This dream was about

I was in a apocalypse, we were staying in a caravan and a sorcerer was protecting all that was left of mankind. One night I wake up for a class of water and I see the janitor hiding money, I ask him what he is doing and he tells me to keep it a secret. I take his hush money and I go and buy my friend a birthday present, I drop it infront of the sorcerer and he finds my secret money too. When he confronts me I run away from him to my friends but they can’t see me. I look down the corridor to see that the janitor is dead and the sorcerer grabs me and cuts my head of using a wire.
