I once had a delirium dream that there were customers coming in and out of my bedroom, taking boxes and returning them empty. I almost phoned my boss and told him, "if you don't get these fucking customers out of my fucking room, I'm going to quit right now."
I'm very glad that when I woke up, I didn't do it. Still phoned in sick though.
I only ever had dreams like that back when I first started as a service clerk (Yes, a bag bitch).
