VISUAL PROMPT

Without describing exactly what you see, write a story, poem, or descriptive paragraph which conjures this image.
Shadow
There was a silhouette in the dark that I could make out
Shrouded by the stillness of the forest
While I laid awake in bed, safe and sound
My eyes peeled to the double-arched window.
I could barely make out the shape of a man
Dressed in black, standing strong and tall
He seemed to be staring straight ahead
His face tipped towards my room's dim glow.
I should be nervous, or at most petrified
Calling someone, anyone, to ask for help
But every part of me is rooted to the spot
As if I am stuck in a precarious limbo.
He tilts his head towards the side, menacingly
Could he sense my probing gaze on him?
Does he realise I'm watching him watch me?
Is he a mere stranger or is he someone I know?
A harsh tug and the curtains fall into place
I'd rest unseen, my thoughts would stay hidden
Those fantasies that awaken in the dead of night
Lingering, lurking like a resounding echo.
Will he act them out and enter my house silently
Or have I created a game of make-believe?
Maybe all this is - is just my imagination
Maybe the man is simply an unwitting shadow.
