A poem I can imagine would be read to young shadow hunters (of my own creation).
Sweet dreams and night terrors.
Be careful what you wish for, not everything is as it seems
When what you see in nightmares, might not just be in dreams
He's hiding in the shadows of all your childhood terrors
At the corner of your eye and trapped inside your mirror
But he's just your imagination, or is he? Aren't all the stories true?
Those shadows in your closet just tempting you, "come through."
