Interacting with Shadow

"I spied my shadow slinking Up behind me in the night, I issued it a challenge, And we started in to fight. I wrestled with that shadow, But it wasn't any fun, ''I tried my very hardest -- All the same, my shadow won."

- "I Spied My Shadow Slinking", from The New Kid On The Block by Jack Prelutsky

An occurrence in most forms of media, where a character who is usually a Cloudcuckoolander or a Dojikko, will very often talk with his shadow like it's a real person.

Contrast: Living Shadow, in which the shadow really is a living being.
