Cerebellum of the Earth

Last night I dreamt that I was on a cruise of Antarctica (not very strange since I have been drooling over Antarctic cruise brochures for two days in hopes of combining it with a trip to Incan Ruins in Peru). Anyway, the polar ice caps ended up being a sham and Antarctica is actually a large rock sitting on a shallow ocean floor. The temperature is warm and I was in my swim suit. As I swam around Antarctica, I realized that it was the brain of the Earth, which controlled the entire ecosystem. As I got closer to the cerebellum, I threw a penny onto the brain for good luck. Lord only knows why I did that. Suddenly I realized I had disrespected the Earth and that a highly advanced tribe of beings would now have to kill me (and that the Earth would also be trying to kill me). I woke up in a cold sweat and had to walk around a bit or I never would have been able to fall back asleep.
