I dreamt that aliens that looked like gremlins were trying to take over the world, and attacking people one on one. See, they were strong, fast, and small, so they could hide easily in the dark and take a person down as soon as their back was turned. But that also meant they had to kill the cats first, since cats would find them. So, my nightmare pretty much ran like a cross between Alien, Gremlins, and Signs. Very tense, don't wanna do that again.
I blame my mom's cat, btw. She's decided that attacking me while I'm asleep is fair game, and I suspect that was the seed for the dream.
