I was the first person to see the thing.
I only became aware of it when the light in my room started to dim. I looked up from my laptop and there it was, a thin humanoid form hunched upside-down next to the lamp.
I yelled. I tried to scamper away but my chair caught in the carpet and I simply toppled over, pulling the laptop down by its cable.
It didn't seem to notice. It fixated on my lamp, gingerly cupping it with charcoal-black fingers as if it was a rare insect. Then, it closed its hands and the light was out.
