Horror Flash Fiction | The Knock

Shen Li lived alone and made it a habit to lock her door before sleeping. One night, she heard a knock. It was slow, a gentle tap-tap-tap, like knuckles lightly rapping the door. She didn't dare to open it. "Who is it?" she asked through the door. No answer. The knocking stopped. Thinking it was a prank, she was about to get back into bed when the knocking started again. This time, it came from inside the room. She froze, slowly turning her head to look at the bedroom door—it was closed, and no one was there. The knocking started again, this time from the closet. She stared at the closet door, her hands starting to tremble. The knocking grew closer, finally stopping. Relieved, she turned to go back to sleep. A soft knock-knock came from right beside her. It was from under her bed.
