Frustration Dreams

Speaking of dreams... Anyone besides me have what I have come to call "frustration dreams?" My frustration dreams are where I am trying to look something up in a phone book, but I can never find the entry because things are not in the right order, or the name is no where to be found or some other glitch in the phone book.

I also remember, as a child, having dreams where I was trying to run away from something that was coming after me, and I couldn't move my feet, or else was moving in a painfully slow way. I don't have those dreams any more. I wonder why.
