What's the setting for your typical bad dreams?

I have eight or ten usual “bad dream” settings or situations. (“Bad dream” is relative for me, because as far as I’m concerned the only really bad dream is one that’s dull and boring.) Three typical locations are classrooms, hotels, and an unknown road somewhere.

Do your bad dreams tend to occur in the same types of locations over and over, or do you get to tour a wide variety of interesting places in your nightmares?
