Weird apocalyptic dream. I was at work, although work was an old building with high ceilings, like a church. During routine discussions, we experienced a moderate earthquake that caused minor damage. In the excitement, after the event, we discover that a small black hole, about the size of a speck of dust, had hit the Earth, and was now swimming around the planet's centre-of-mass, causing horrifying instabilities. The moon was getting pulled in slightly closer, causing the tides to rise considerably. This nightmare end-of-world situation was apparently going to right itself when said black hole evaporates in a few days. We were left with a sense of dread, but with the feeling that if we just maintained a stiff upper lip, and kept on high ground, we'd make it out of the other side.
