Nightstalker

In a calm moment a chance reflection
  revealed you

A transparent dark form
  superposed on my own,
    in a mirror

Changing dark changes
  from black blotches
    to naked fangs
      to unspeakable

Lurking monster,
  alert for worship
    alert for blood -- 

Dim demon face
  now you are visible.

You, formless black slime
  in which I drifted, blind, 
    dreaming of roses

Are not alive. 

You, ancient gods spawn
  of rage, spawn of hate,
    spawn of "me" and "mine"

Cleverly hide in the Most Obvious Place.

You, deadly computer program
  virus parasite,
    energy drain

Are part of me.

I am not free
  but I am aware.
