DREAM ANALYSIS, ANYONE?

I had the most disturbing dream last night. It went on for hours.

Mike kept telling people his "favorite new joke," and I kept walking around saying, no, no, Mike, this is the stupidest joke EVER.

The joke went like this:

What is the difference between Godzilla and a cow?

Godzilla is a giant green monster who devastates Tokyo, and a cow isn't.
