Halloween/Spooky Microfic

I have never written microfic before, but S.E. Sinkhorn over at Maybe Genius is running a microfic contest.  I figure today is as good as any to try something new.  The rules are essentially - write a story in 140 characters about something spooky Halloween-esque and tag it #Hallowfic on twitter.

Here's the full blogpost with the rules in more detail.

And here's my entry:
Lights turn on; a scream. I race inside; turn on the lights. My body, soaked in blood; how did it get here before me? I scream.
