I spent much of the next day lying about and continuing my mental movie, building a fictional friendship with an actor I'd never met. I asked my sister if she thought I was taking the fantasy too far, but she assured me that as long as I could tell real from imaginary, there wasn't anything to worry about.
Late that night, I got up from my bed to use the bathroom. As I walked down the hall, I caught a glimpse of someone standing in an open doorway. I froze. Before I could decide what to do, a passing car's high beams shined through the window, illuminating the doorway to reveal empty space. I continued to the bathroom. As the florescent lights flickered into life, I passed the mirror. For a moment, I could have sworn my reflection was replaced with someone else's. He did not look happy.
Unnerved, I did my business and hurried back to bed. I kept my eyes down while passing the doorway again, but I couldn't keep from glancing behind me before entering my room. A thin man strode down the hallway towards me. I rushed into my room, closed the door, and locked it. I took a breath, convincing myself that it was just shadows...and that the lock was secure.
"You shouldn't make up stories." I wheeled around to see David Tennant standing across from me, face grim. "They might not like the way you tell them."
