I saw enough dark, spooky elevators in one hospital I did Y2K work at. The hospital had expanded in stages, and wings were added at odd angles, and eventually joined to form a sort-of hollow square. Most elevators were small, and tucked away in odd alcoves off the hallways. The basement was dark and gloomy, and there were other elevators that that had been abandoned, with the openings bricked-up and covered over on the upper floors.
The place was weird in other ways, too. On an upper floor, a proposed operating room would take the entire width of the building, forcing people to walk all the way around the hollow square to get from one side to the other. So, just before the OR, they knocked a hole in the wall on the courtyard side, built a parapet along the wall, and then entered the building again just past the OR. You're walking along, the make this turn, and you're eight floors up with just a handrail and some windows one one side, with brick wall on the other.
I have elevators and escalators in dreams, too. But they're usually super-deluxe models, or totally weird, like split-level elevator cars that also run horizontally, and along the outside surface of the building.
Sometimes my weirdest dreams end too soon for me to make sense of. The other night, I was in some sort of jeep-like vehicle with other guys, driving down a long lane of trees in some sort of semi-arid country. We get out, and sit in grandstands that face a field about the size of a football field, but it's surrounded by a 20-ft-tall chain link fence. There's a few guys walking around in the field, and a couple of things on the ground.
I'm starting to get curious about what's going to happen, when I notice that everyone else is in some sort of military camouflage, and they don't look like nice guys. So what's going to happen on the field, and what am I suppposed to be doing there? That's when the alarm went off.
If the situation had turned dicey, I'm sure my subconscious would have made sure I was heavily armed. Even in my worst nightmares, I manage to come up with enough firepower to at least break even.
