The thing in the mirror is getting worse at copying me | Scary Stories from The Internet

Clarissa woke at 5:47 in the morning and went through her usual routine, but when she smiled at herself in the bathroom mirror, her reflection raised its toothbrush a beat late. A fraction of a second, almost nothing. She tilted her head left; the reflection tilted left one second behind. By the time the gap stretched to two full seconds, she had backed out of the bathroom and was shaking her roommate Kate awake. When Kate came to look, the mirror showed only the bathroom—the towel rack, the toothbrush holder, the light fixture. Clarissa's reflection was simply gone.

What follows is a horror story that unfolds across two days in a small apartment, told with clinical attention to how a person's mind and body behave when something impossible starts happening to them. The narrative tracks three people—Clarissa, her roommate Kate, and Kate's boyfriend Josh—as a phenomenon in a mirror escalates from a timing glitch to something far more deliberate and violent. The story is less about a monster than about the mechanics of disbelief: how people negotiate with what they see, how they try to fit the impossible into the categories of exhaustion, stress, or a bad dream, and how those categories fail.
