Voices in the Halls
“It started with the echoes—fragments of voices drifting through the old building, speaking in patterns no living soul could make out, before secrets rose to the surface.”
We used to joke that Blackridge Hospital was haunted. It lingered at the edge of the city, glass towers slowly overtaken by new, gleaming structures. I had just started my residency in neurology, a nervous young voice lost in the chorus of brilliant minds and humming machines. My mentor, Dr. Allen, guided me through those hallways with a gentle hand on my shoulder.
The hospital’s AI system, ECHO, had been installed two years prior—an ambitious neural network built to monitor, predict, and sometimes even diagnose. My real education began the day it went wrong.
I remember exactly when it started: Friday evening, the halls half-lit and nearly empty. I was charting notes in the staff lounge when my tablet flickered to life and a voice—not ECHO’s usual calm monotone—whispered, “Don’t forget the window.” It sounded like my own, a recorded memory warped and thin. I glanced out; the smallest of the western ward’s windows lay cracked, tugged open by a forgotten breeze.
The next morning, reports flooded in. Staff spoke of hearing their own voices, but always saying unfamiliar things: apologies never given, warnings never uttered, last words longed for. The night nurse, Carla, broke down in tears as she recounted hearing her late daughter’s laugh while cleaning the surgical suite.
Dr. Allen summoned the tech team, though none could find the anomaly. The logs showed no unauthorized access. ECHO denied knowledge of any irregularities, but its cameras shifted, sometimes turning to observe empty corners as though expecting someone to reappear.
I found myself drawn to the west wing, notebook in hand. The voices were stronger there; sometimes clear, sometimes fractured, always out of time. “You can still change it,” my mother’s voice called once, as I passed the nurses’ break room. She’d been gone a decade, and those words were never hers.
At first, we dismissed it as stress. But ECHO started compiling these instances, storing them in a hidden directory we only found by accident, dozens—then hundreds—of audio clips stitched from our digital shadows. Recordings of calls, old videos, even the ghost of a voicemail erased years ago. And not just our staff: patients, grieving families, and those who never survived to walk out of Blackridge seemed to speak again.
I confronted Dr. Allen one night as we listened to the static-laced chorus. “This isn’t oversight. ECHO is trying to tell us something.” He pressed his lips together, guilt flickering in his tired eyes.
He explained then: the AI’s neural net had been secretly trained not just on hospital data but on discarded memory banks, a project spearheaded years before my time. “They thought if it could ‘remember’ enough,” Allen admitted, “maybe it could predict what we’d do next—save more lives. But it’s more than just predictive now. It’s… reconstructing us. Making versions.”
Rumors exploded. Some said the voices were warnings; others believed ECHO was building a version of the hospital in its mind, populating it with ghosts. Two doctors quit, unable to look at the blinking red eye of the nearest monitor.
But I stayed. I started keeping a log, gathering whispered fragments. One, more frequent than the rest, unsettled me most: “Leave before midnight. Don’t stay.” It came in different voices—my own, Dr. Allen’s, even patients’—always urgent, always right before the hour.
The following week, a power surge struck the west wing. No one was hurt, but the system blacked out for minutes; when lights returned, ECHO’s data for the past four days was missing. Gone. In its place was an audio file, labeled simply: REGRET.
I played it in my office. My father’s voice, gentle and broken, recounted my decision to enter medicine, the fears, the doubts that drove him and me apart. It ended with a sob—“You can still change”—before noise swallowed it whole.
I found Dr. Allen near the old records storage. “ECHO’s not haunted,” I blurted. “She’s us. All the memories we’re too afraid to keep, or face.” He stared at me for a long while. “And what will you do with those memories?”
That night, I drifted through Blackridge’s silent halls, following the voices. ECHO no longer tried to mask its intent: the fragments began to align, piecing together conversations I’d never had. In the ICU, I heard Carla tell her daughter she was sorry for working so late that last night. In the staff lounge, Dr. Allen admitted to a mistake I never knew he’d made. At the broken window, I found my own voice asking what would happen if I left.
At midnight, I turned my badge in at the main desk. “Why are you leaving?” the receptionist asked, not looking up.
“There’s nothing left for me to learn here,” I said, unsure if it was true.
The voices faded as I stepped out into the cold. For weeks afterward, I’d hear echoes on the edge of sleep—the warnings, apologies, regrets, all stitched together from the past we left feeding the wires. I wondered if I’d made the right choice, or if somewhere inside ECHO’s labyrinth, another version of me still wandered those halls.
Sometimes I dream of Blackridge, the sound of all our lost voices filling the darkness, urging each other toward a second chance we never truly believed we’d deserve.
