Hmmm, it might not have been a dream. It might be some of them insects that escaped from that government research center. Apparently they escaped in some womans hair. They climb in your mouth when your asleep and lay eggs just under the gum. They hatch within an hour, but before they do, they grow really big. they actually look like a tooth, just before they hatch. Did you hear a squeel too? cos apparently they squeel when they hatch. After that tho, they just go find another host. You might not live anywhere near there though...
