What a strange one

Yestarday I had that weird dream where : I was in a high-tech building (with cool clothes) with a group of police officers (if you know Chicago PD then that's good!) and there was a fire on a server floor (higher in the building). Apparently I was working as a server maintenance and (somehow) the elevator was working and the police was evacuating the building except me. I was on a floor with some police officers and some firefighters was on the other side of the floor (the elevator is in the middle of the floor and have a two-side opening). As I was talking with police officers of how I was going to the server level, Jay (or Jake from Chicago PD) was on the other side of the elevator was being a pain in the ass repeating "You can't go up" but I got in the elevator anyway. When I got in, he was pushing a button stopping the elevator to move on then I told him "stop pushing that button before I broke your fingers". We got into a fight until I woke up.

Can someone explain that?
