The apocalypse

Most of my dreams take place during or after an apocalypse. i had a dream once that i was in a hotel in new york. i was packing up to leave the country. due to large sinkholes. i noticed a rat slowly crawling across the floor. i could see the shape of it's ribcage and spine, it was sooo skinny. on my way to the plane, i found out from a news report, that china had had a catastrophic sinkhole. well, then i had nowhere else to go. so i ended up making my way west. i ended up in Sacramento, CA. every so often, i would walk past a sinkhole that would be a couple of acres wide. don't remember much more than that...
