Nap dream.

I'm at work, and there's a small group of 3-4 different dinosaurs roaming around. All are different kinds, but all are big, nearly reaching to the building. One of my coworkers, sitting just a few feet from me, is friendly with them, petting them whenever they stop by and whatnot.

They're basically just roaming the building, primarily the floor we're on. Whenever they come by my friendly coworker (which is somewhat often), they would growl and roar a lot, scaring me and making me cover my ears due to how loud it is. Couldn't really do my work because of it.

Eventually, they start exploring other floors. It's at this time that me and most of my coworkers (except the friendly one) decide to try to escape to another floor. So we get to the elevators and go up to every floor, checking and making sure there are no dinosaurs on any of them. Most of them were fine, but one (I believe it was the 5th) did, and it saw us as soon as the doors opened. It started charging at us, and we clicked on the close elevator buttons so many times. We barely made it.

When we got to the top floor, there were no dinosaurs, so we decided to get off. I, however, was a bit slow, and by the time I tried to get off, the elevator was already decending and the doors were closing. I ended up hanging on and dangling down the elevator chute, several floors below me. Eventually, I let go, but the elevator was just on the floor below me so I only dropped a few feet. I was able to get to safety then.
