Fear is usually something we associate with the unknown with the things that go bump in the night or the shadows that stretch too long under a full moon. At thirty-four years old, I believed I had a firm grasp on the boundaries of reality. I am a mother who relies on instinct and logic to navigate the complexities of raising an eight-year-old alone. My son Sam has always possessed a vivid imagination, the kind that turns a discarded cardboard box into a spaceship and a rainy afternoon into an epic quest. When he first started whispering about someone watching him at night, I dismissed it as the standard fare of childhood nightmares. I thought I could solve the problem with a brighter night light and a gentle kiss on the forehead. I was wrong.

Sam didn’t play for attention. He didn’t scream or throw tantrums. Instead, he spoke with a chilling, quiet certainty that eventually made my skin crawl. He would stand in the hallway in his dinosaur pajamas, rubbing the sleep from his eyes, and state as a matter of fact that a presence stood in his room when the lights went out. By the fourth night of his persistent claims, I decided to conduct a thorough investigation to provide him with the peace of mind he deserved. I checked the closets, moving the hanging shirts to prove no one was hiding behind them. I crawled on the floor to inspect the space under his bed, finding nothing but stray socks and comic books. I double-locked the windows and tested the heavy deadbolt on the front door. Everything was secure.
