"I'm as real as you make me out to be."

The nebulous humanoid form marred the dimly lit room, his feverish voice echoing in your unstable mind. The appearance was a shifting, ever-changing tableau of faces, the very boundaries of reality wavered around you.

He was your darkest secret, your mental illness made corporeal, and he knew you better than anyone. He was everywhere and nowhere at the same time - a figment of your imagination, yet all too real in the depths of your psyche.
