Anxiety Dreams

I had that dream again -- it's always a different dream, but the basic conceit is the same. I need to get somewhere, urgently, but when I open a door to get there, there's another door behind the door (like in that cartoon) and another behind that one, and so on.

Or I'm climbing stairs, except they keep running out before I reach the place I'm trying to get to.

Or (last night) I have to take elevators, but they won't stop on my floor; or they don't go to the floor I need to reach; or the elevator doors open, but there's no elevator, or it's stalled halfway between floors. Or I finally reach the right floor, but the person who needs to sign off on my paperwork is gone, and no one know when he'll be back.

I mean, the symbolism is obvious; but they're still stressful dreams.
