When my friend Marta convinced me to join her and her cousin Diego on an overnight expedition to the abandoned San Vicente Tuberculosis Sanatorium, I agreed mostly out of curiosity. I’ve always been fascinated by the paranormal, but I’ve never actually seen anything that would convince me. The sanatorium had been closed since the 1960s, perched on a hill overlooking the fog-choked valley, its windows like hollow eye sockets. We packed flashlights, a digital recorder, and a camera, and set off as the sun dipped behind the mountains, leaving the world in a cold, blue dusk.
Inside, the air was thick with the smell of mildew and decay. Our footsteps echoed on cracked linoleum. The walls were covered with peeling paint and graffiti, but some corridors still had faded signs pointing to ‘Solarium’ and ‘Occupational Therapy.’ It was a sad, lonely place. Marta, the true believer, had brought a spirit box. Diego just wanted to prove it was all nonsense. I was the neutral observer, hoping for something, anything, to tip the scales.
We wandered through the main hall, a cavernous space with high ceilings and shattered windows. The wind whistled through, creating a low moan that made my skin prickle. I pulled out my phone to check the time — it was 11:47 PM. I noticed my battery was at 87%. Ten minutes later, as we climbed a narrow staircase to the upper floor, I felt a sudden, icy presence behind me. It was as if someone had walked up and was breathing on my neck. I spun around, flashlight beam cutting through the dust, but there was nothing. My heart hammered. ‘Did you feel that?’ I asked. Marta nodded, her eyes wide. Diego shrugged, but I saw him glance back nervously.
I checked my phone again — it was at 12% and dropping. ‘That’s impossible,’ I muttered. Diego’s phone was fine, though. Marta’s was fine. Mine was draining like a sieve. The screen flickered, showing a static-like distortion, then died completely. I shook it, but it was dead. I felt a sudden chill, as if the room’s temperature had dropped several degrees. The air grew thick, and the silence became oppressive.
We decided to head down, but our path took us down a long corridor. On our left, there was a medium-sized room, larger than the patient rooms we’d passed. The door was half open. Through the gap, I saw a broken piano, overturned chairs, and a layer of dust coating everything. It must have been a recreation room. Marta whispered, ‘Should we go in?’ Diego said, ‘No, let’s keep moving.’ But I felt compelled, as if something was pulling me toward the doorway. I stepped closer, and that’s when I heard it — a faint static, like a radio tuned to nothing, coming from inside the room.
I pushed the door fully open. The static grew louder, almost like a voice buried beneath the noise. I stepped inside, my flashlight sweeping across the walls. They were covered in old patterns of fading wallpaper, peeling in long strips. In the far corner, a single chair faced away from us. The static seemed to emanate from it. I took a step closer. The floorboards creaked. And then, the chair slowly, very slowly, swiveled around.
There was no one in it. But on the seat, there was a small, tarnished locket, gleaming in my flashlight beam. I leaned down to pick it up. As my fingers closed around the cold metal, the static reached a deafening crescendo. A gust of wind slammed the door shut behind us. I spun around — Marta and Diego were frozen, their faces pale. The static stopped as abruptly as it began, replaced by an echoing silence. In the silence, I heard a child’s laughter, soft and eerie, from the hallway outside. We bolted.
We ran down the corridor, our feet pounding against the floor, not daring to look back. We burst through the main entrance into the cool night air. We didn’t stop until we reached the car and sped away, the sanatorium disappearing in the rearview mirror.
Later, at Marta’s apartment, we sat in stunned silence. I had the locket in my pocket — I’d forgotten to mention it. I pulled it out and opened it. Inside was a faded photograph of a young girl with a smile that didn’t reach her eyes. On the back, in delicate handwriting, was a name: ‘Lucia.’ And a date: 1954.
A week later, my phone turned back on. The battery was full. But when I plugged it in, I noticed a single audio file saved on it, one that I hadn’t recorded. It was a recording of static, but beneath the noise, a voice — a child’s voice — singing a lullaby I had never heard before. I still don’t know what happened that night. But I know I’m not a skeptic anymore.
