Not sure if it was the result of a meteor impact or if it was a "natural" superquake - but in my dream there was a quake at my parent's house in south GA - it was pretty severe which is unusual for that area since its all sand (shaking wouldn't travel at all unless extreme.)

The sky went totally dark and I could see SO MANY stars, and lightning started striking and flashing like crazy all around, then a few seconds later the sun came back out. This dark and light transition happened about 10 or 20 times during the quake until finally it settled on light with rain (the sky was a little cloudy before, but not rainy.)
