Found Poetry

From a scrawl in my Writing Notebook, this time.

They come in when it gets cold.
The past few days I've heard them in my office.
A faint buzz from the light fixture.
Is it a fly or a spark?
And then in the breakroom, a ghost of sound
from the coffeemaker, or window, or maybe
it is the light fixture here too.
And back in Cold Storage in the dust
when I was looking for the Petri dishes.
Everywhere I go, following me,
The faint ghostly buzz, perhaps heard, perhaps not.
It feels like there's a story in that,
and chances are it's a very creepy one,
But I have no idea what.
