It would be interesting to know what the "anxiety" dreams are, in different cultures.

Here's what I'd say are some classic anxiety dreams:

• you find out there's an exam in the class you're taking, even though you've never gone the class, and kind of forgot about it (i still have this, even though I don't think I was anxious at all in college)
• There's an emergency and you have to make a phone call. But the phone doesn't work.
