I think I had the weirdest of all weird dreams last night. I wasn't even in it; dreamt from third person perspective (movie style).
There was a large meteor that impacted with a plane, the meteor caused the water level in the oceans to rise tremendously causing 500 foot tall waves to impact with land. There were very few pockets of land that remained dry.
Over the course of millenia, crabs gained in size until that had no natural predators, not even sharks could compete with them. Eventually they took to land and overthrew the humans that survived and remained.
The crabs started to kill the humans and loved the taste, and continued their reign agaisnt the human species. Eventually, the humans were all eaten and nothing was left of our species except the few buildings that remained.
