Marta had been home from the university library for barely an hour when she remembered the assignment due Friday. She had left her bag by the door, her notes scattered across the coffee table, and her laptop charging in her room. She’d meant to start the research paper on coastal erosion, but her mind had drifted to the strange noises she’d heard earlier—a faint scratching, like dry leaves against the window, though it was a windless evening. She shrugged it off.
She went to the kitchen to make tea and found her sugar bowl on the counter, the lid slightly ajar. Inside, instead of sugar, there was a fine, gray sand, mixed with what looked like tiny bone fragments. She recoiled, her stomach turning. She hadn’t used the bowl in weeks; she preferred honey. She replaced the lid and decided to ignore it, blaming a prank from her roommate, who had a dark sense of humor. But the house felt heavier, the air thick with a dusty, mineral smell.
Later, as she settled on the couch with her notes, she realized her laptop was not on the couch where she’d left it. She checked her bedroom—nothing. The kitchen—nothing. The bathroom—nothing. A chill ran down her spine. She called out, ‘Hello? Anyone home?’ Her voice echoed off the walls, met with silence. She did a quick sweep of the apartment, even checking the closets and under the beds. Empty. She convinced herself she must have misplaced it, perhaps in a moment of distraction.
She sat back down, trying to focus. Her pen was missing now. She had placed it on the coffee table; now it was gone. She felt a wave of unease. She got up and walked to the pantry to get a snack, and as she opened the door, she froze. Her laptop was on the top shelf, nestled between a bag of flour and a jar of peanut butter. How had it gotten there? She grabbed it, her hands trembling, and as she turned, she noticed the sugar bowl was on the floor, its contents scattered in a thin line leading to the back door. The grains shimmered with a faint phosphorescence, like the dust of a sea creature.
She set the laptop on the counter and knelt down to examine the trail. It seemed to move as she watched—a slow, creeping advance, as if the sand was alive. She backed away, a cold dread seizing her chest. She ran to the living room to get her phone to call her roommate, but her phone was not on the couch. She started to panic. She searched frantically, tearing through cushions, checking the bathroom again. In the bathroom mirror, she caught a glimpse of something behind her—a shadow that lingered a beat too long. She spun around; nothing. But the mirror now had a handprint in the condensation on its surface, though the room was dry.
She fled to the kitchen, but the back door was now ajar, and the sand trail led outside. She slammed it shut and locked it, her breath ragged. She felt a sudden urge to check the oven. She slowly opened the door, and there, sitting on the wire rack, was her phone, the screen glowing with a message from an unknown number: ‘Your homework is waiting.’ She jumped back, a scream caught in her throat. She slammed the oven door shut and turned to find her notes from the coffee table were now arranged in a neat pile on the floor, with a new page on top. It was blank.
She grabbed her laptop and her notes, intending to leave, but as she reached for the door, she heard a sound from the bedroom—a soft, rhythmic brushing, like sandpaper on wood. She didn’t want to go, but something compelled her. She crept down the hall and peered into her room. The window was open, and a fine sand was blowing in, forming a mound on her pillow. On the blanket lay her pen, and beside it, a single grain of sand that seemed to pulse, emitting a faint, rhythmic glow. As she watched, the grain split, and a tiny, silvery creature crawled out, no bigger than a grain of rice, with many legs and no eyes. It skittered across the blanket, leaving a glistening trail.
Marta didn’t wait. She turned and ran, bursting out of the apartment, down the stairs, and out onto the quiet street. She didn’t stop until she reached her car. She sat there, hands shaking, staring at the apartment building. Through the window of her second-floor kitchen, she could see a pair of glowing pinpricks, like eyes, watching her. She started the car and drove, but she knew she couldn’t escape. The sand had gotten everywhere—in her hair, under her nails, in the seams of her clothes. She could feel it shifting, moving, as if it was crawling over her skin. She pulled over and checked her phone, which she had snatched from the oven. The message had changed: ‘You brought me with you.’ She looked in the rearview mirror and saw a thin layer of sand coating the back seat, and from it, a tiny claw reached up.
She screamed and threw the phone out the window. She drove until the gas gauge hit empty, ending up at a beach she knew from childhood. She got out, her shoes sinking into the cold, wet sand. She walked to the water’s edge, hoping the sea would wash it all away. But as the waves receded, she saw that the sand on the shore was not normal; it was gray, and it writhed. The entire beach was alive with the same grains, and they were beginning to rise, forming a shape—a humanoid figure, featureless, but reaching for her. She wanted to run, but her feet were rooted. She looked down, and her own shadow had turned gray and was pulling away from her, like a tide. She opened her mouth to scream, but only sand came out.
The next morning, her roommate found the apartment empty. The only thing out of place was the sugar bowl, full of clean, white sugar, sitting on the kitchen counter. On the floor, a note scrawled in handwriting that was not Marta’s: ‘She forgot her homework.’ The roommate shrugged and went to class. On the beach, a few miles away, a new sand dune had appeared, perfectly shaped, and if one listened close, they could hear a faint, rhythmic brushing, like a whisper of a student trying to remember something important.
