I was in the kitchen, with Karen and some friends watching TV in the living room. As I passed by the sink, I noticed that it was making a quiet, high-pitched noise, as though metal were constantly scraping against metal.
I turned on the faucet, to see if that was the cause, and instantly there was a banging noise. I thought it was the pipes banging, but then I realized it was the downstairs neighbors (which, in real life, don't exist, as I live in a house. But this is dreamworld, where such things are infinitely malleable).
For some reason, the banging filled me with a nameless dread. I felt the blood drain from my face, and a chill spread over my body, and then I found myself wide awake in bed, unable to get back to sleep.
So here I am, posting at 4:10 AM. Wheee.
