Some places are meant to stay hidden. Beneath our feet lies a world of endless darkness, a place where sunlight never reaches, where strange sounds echo through the darkness. For centuries, people have entered caves searching for answers. Some came back with stories they could not explain. Others claimed they weren't alone down there. In this episode, we're exploring eerie counters, unexplained creatures, and the unsettling stories from the darkness below. I'm Leon Leighton, and this is the real unexplained stories. Story 1. The tunnel that shouldn't exist by Ethan. My name is Ethan, and what happened to me in the woods near my hometown is the reason I don't go underground anymore. I don't go exploring old mines. I don't step inside drains or tunnels, and if I ever hear a single knock in the dark, I move. Because something down there answered me once, and it wasn't human. In 2014 I was 19 and home for Christmas. My older brother Luke was already back and excited about some tunnel he'd found deep in the woods. He said it wasn't a normal tunnel. He said it was straight, clean, and looked way older than anything around here. I didn't believe him at first. He always likes to make things sound bigger than they are, but he wanted me to go down with him, and like always, I said yes. We walked through the woods until he pointed out a small doorway shaped hole hidden behind a thick bramble bush. You wouldn't see it unless you were right in front of it. The cold air drifted out of the darkness, not winter cold air, deeper than that. It felt like stepping next to an open freezer in the middle of the night. Luke ducked inside and I followed. The tunnel ran straight ahead, carved through solid stone, no bricks, no wooden supports, just smooth rock, like someone had sliced it clean with something sharp. But the markings were the worst part. Scratches carved into stone every few steps, not letters, not symbols we knew, just strange lines, curves, hooks, all different. And the deeper we went, the weaker our torches got. The beams only lit a few meters ahead, and then the light died, like it was being swallowed by the dark. That should have been the moment we turned around, but we didn't. Around ten minutes in, I heard it. A single knock, a tap. I froze. Luke he nodded. Yeah, it happened last time to me too. That's someone, I whispered. Someone's down there. No one answered when I shouted. Before I could say anything else, another knock came. Closer now. My skin went cold. We kept walking a little faster, and then the knocking came again and again, always slow like it was waiting for us. After almost twenty minutes the tunnel opened up into a small square room. The markings covered the walls now, hundreds of them, scratches over each other, like layers after layers of carvings. Luke walked around the room, shining his torch on everything. That's when I noticed something he didn't. Some of the scratches were fresh, new and clean, not worn down like the others. Someone or something had been carving in here recently. I just felt sick. Then my torch caught something in the far corner, another tunnel. But this one wasn't smooth or straight. It looked torn out of the rock, rough and uneven, like something had forced its way through the stone. Ice cold air drifted out of it. I didn't want to go near it. I didn't want to look at it. And then something inside the dark hole moved. A shape, tall and thin, and wrong. I stepped back fast. Luke saw it too, his breathing changed. Then the knocking started again, but this time it came from both tunnels, one behind us, and one from the torn passage. Tap tap tap, soft and slow, answering itself. The sound didn't echo, it vibrated through the stone. That's when the whole place felt like it was holding its breath. We didn't talk, we didn't look back, we just ran. The knocking followed us straight away. Not a single knock's now, dozens of sharp hits, chasing us through the tunnel fast, too fast. Like something was moving through the stone beside us. My torch flickered. The darkness fell thicker. Something cold brushed past my ear, and right then a knock sounded right next to my head.
unknownTap.
SPEAKER_00I shouted, and I ran faster. The tunnel felt twice as long on the way back. My lungs were burning. My eyes just kept watering. The knocking got louder and closer like it was right inside the walls. Then I saw a grey light ahead, the exit. We burst out through the brambles, tearing claws, scratching arms, but we didn't stop until the trees opened up. Only then did the knocking stop. We stood there shaking, trying to breathe. Luke lifted his torch to check the cut on his jacket. Then he looked at mine. Ethan, look at your sleeve. A mark, a long curved scratch, with a hooked end. One of the carvings from inside the tunnel, edged clean into my jacket. I tore the thing off like it was on fire. One week later, Luke went back. He told me after. He wanted four o'clock as proof, but he never got inside. The entrance had collapsed, dirt and stone and roots everything pushed down over it. He said it looked like something sealed itself in, or sealed something out. We never went back, but I still have that jacket. It's stuffed in a box at the back of my wardrobe under old jumpers, and every time I check it, that marking looks deeper, like whatever carved it is still carving. Slow and patient and waiting. The Voice in Shaft 9 by Helen Hi, I'm Helen and years ago I worked as a safety checker at an old coal mine that shut down long before I was born. Most of my job was above ground, checking gates, fences, signs, nothing dangerous. I never went into the mine, not once, until one night I had to. One of the movement alarms went off inside shaft nine. That alarm meant something had moved underground. Could it have been a fox or a collapse or someone sneaking in? I should have waited for the main team, but I didn't, and that was the biggest mistake of my life. The lift didn't work anymore, so I had to use the long metal ladder. The further I climbed down, the cooler the air became. By the time my boots hit the bottom, I could see my breath in front of me. The tunnels stretched both ways, tight walls, low ceilings, old coal dust covering everything. I called out Hello is anyone down here? A moment paused. Then from the darkness to my left my own voice answered Hello is anyone down here? Same tone, same rhythm, but delayed, far too delayed. It wasn't an echo, it was copying me. My stomach dropped. I called again If someone's hurt, speak to me. Another pause. Then my voice repeated back. Flat, too clear and too smooth. If someone's hurt, speak to me. That was when I realized I wasn't alone, and whatever was down there was pretending to be me. I walked towards the left tunnel, slow and careful. My torch didn't reach far. The darkness swallowed the light like thick smoke. Then I saw something in the dust on the floor. Finger marks, four long lines dragged across the ground, like something had been crawling. They went along the floor and up the walls, then vanished into the dark. A whisper slid through the tunnel behind me.
unknownCold.
SPEAKER_00Not my voice, not anyone else's, just wrong. I turned shining my torch, but there was nothing there. But when I turned back, something ahead of me moved, a shape, tall and thin, standing still in the centre of the tunnel. I raised my torch slow. At first I thought it was a person, but the shape wasn't right. The head tilted too far to the side, and the shoulders didn't match. One arm hung lower than the other, almost reaching the floor. Then the thing stepped slowly sideways, smooth and gliding, like its feet wasn't touching the ground. It tilted its head again. Then it spoke, but not in my voice, in my dad's voice. Come on now, don't be scared. My breath caught in my throat. Nobody else knew he used to say that to me. The creature took one slow step forward. The light from my torch hid where its face should have been, and the beam just vanished, like the surface swallowed it hole. Then it whispered, mimicking me this time. Come closer. That was enough. I turned and I ran. I ran back up the tunnel, keeping the torch low so I wouldn't see how close it was. The creature didn't run. It scraped along the wall behind me, long claws dragging in one slow, steady rhythm. Halfway back it whispered from behind Don't leave. I hit the base of the ladder and climbed so fast my gloves ripped, half up the ladder. The ladder shook hard, like something below had grabbed it. A deep breath rose from the darkness, long, wet and heavy. I didn't look down. When I pulled myself out of the top and turned around, everything went silent. There was no scraping, no breathing, just a cold black shaft behind me. I shut the cover and didn't go back. The next morning the company welded the entrance shut, with no explanation, no debate. They just sealed it. Two weeks later I opened my locker at work. Inside was an old miner's helmet covered in black dust, and across the top of it four deep finger marks, the same shape as the ones on the tunnel floor. I quit that day, because whatever was down in shaft nine, it wasn't a person. It wasn't an echo, and it wasn't stuck. It was waiting, and it wanted me to come closer. The knock beneath the water by Lewis. Hi, I'm Lewis and this is my story. About ten years ago I worked nights as a lock keeper on the canals in Staffordshire, mostly around the old Creswell stretch. If you know the area you'll know the Creswell Canal Tunnel, long and narrow and always colder than it should be. Most people think canals are peaceful, but the tunnels they have their own rules, and one of the rules every worker learns is this don't walk the tunnels after dark, not alone, not ever. I broke that rule once, and I regretted it. It was close to midnight when the call came in. A boater reported something hitting his narrow boat hard inside Cresswell Tunnel. He thought a beam had fallen or something big was floating in the water. He wanted someone to check it before morning. No one else was on shift, so I grabbed my torch and a long pole and went in. You feel the temperature drop the moment you step inside. Cold air runs along the water like a breath. The sound changes too. Echoes stretch in strange ways. About fifty meters in the canal water beside me were completely still. Not quieter, still. Canal water never does that. Then I heard something knock on the wall of a boat that wasn't there. Knock. Completely heavy, like a fist hitting metal. I aimed my torch at the water. There was nothing there. I thought myself it was just a tunnel settling. I kept walking. A minute later I heard it again. Knock knock. Two this time. Right beside my boots. I stepped away from the edge. The water rippled. Not like a drip, but like something had moved underneath, sending wide circles across the surface. I crouched and lowered my torch to the waterline. The ripples froze instantly. Then a hand rose from under the water, pale and thin, with long fingers stretched wide. It pressed itself against the stone wall under the water, gripped it like it wanted to climb up. I stumbled back so fast I hit the opposite wall. The hand slid away without a splash, like it was never there. I knew I shouldn't have turned back, but then a voice called out from the deep in the tunnel. A man's voice. Maid, can you help me? It echoed strangely, not coming from ahead, but bouncing off the water beside me. Maid, please. I shouted Where are you? Nothing. Just the soft sound of something brushing the underside of the tow path, slow and dragging following the curve of the wall. Then the voice called again closer this time. Come here. But there was no panic in it. No fear. It seemed like someone pretending to sound worried. I backed away from the water. A moment later something floated into my torchlight. It was slow and silent. At first I thought it was debris, then it lifted straight up. A long head rose from the canal. Only top half showing the skin looked pale and stretched, tight against the skull. The face was too long, the mouth too wide, and the eyes stayed just under the surface watching. The mouth opened and water poured out into a slow stream, and then that same calm voice, it said Come here. My whole body went cold. I didn't move. The thing tilted its head. It was confused, like it expected me to step closer. Then it slid back into the water without a single sound. I took a step back, and then the knocking started again. Not slow this time. It was four knocks, fast and hard, blows from under the water, keeping pace with me as I backed away. Then something hit the underside of the tow path. So hard the stone shook beneath my feet. I just ran. My torch beam shook widely as I sprinted for the exit. Behind me the water churned, not waves, but something swimming fast. Far too fast for a person. Just as I reached the mouth of the tunnel, a pale hand slapped the stone right beside my boots. Long fingers, a tight grip, with dripping water from them. It scraped downwards, then slipped back into the dark. At sunrise I came back with two other workers. We checked the tunnel together. The water was calm, echo normal, nothing strange, but halfway through we saw something on the wall, long finger marks. Five of them dragged down the stone, straight into the waterline. That spot was far too deep for anyone to reach without going completely under. We never found an explanation. I didn't tell them what I saw. I quit the next month, and now when I walk near the canal, I always listen for the one thing that tells me I'm not alone, a knock below the water. And if you hear it, don't answer it, don't look. And if someone calls for help from the dark water beside you, keep walking because some voices in tunnels aren't human, they never were. I grew up near the south coast, not far from an old World War II defensive line. The countryside down there is full of hidden things, like pillar boxes, bunkers and half buried storage rooms. Most people know about those. What they don't know about are the tunnels underneath, hundreds of metres of them, dug by hand in the early nineteen forties. Most were sealed after the war, but one of them wasn't. The locals called it the Southwick Tunnel, a long straight passage where troops once waited for orders. I'd always been curious about it. It was fenced off years before I was born. I never planned to go inside, but last winter, when a dog walker went missing near the old field entrance, the police asked for volunteers to help search. I knew the area well so I joined in, and somehow I was the one sent to check the old tunnel. If I'd known what was waiting in there, I would have run the other way. Inside the tunnel, I climbed through the collapsed fence and found the entrance half buried under ivy and soil. The metal door was rusted open, hanging off one inch. Cold air poured out of the darkness. Not a normal cold air, it felt heavy, like it was pushing back. I stepped inside with my torch. The beam stretched a few meters, then vanished into black, like the darkness swallowed it whole. The tunnel walls were all brick cracked. The smell was thick, damp earth, rust, and something else I couldn't place. Something still and old. I called out for the missing walker. My voice echoed once, then again, then again, soft each time until it just stopped. The silence that followed felt wrong. Not quiet, just wrong. I took a few steps deeper, and that's when I saw the first light. A tiny flicker at the far end of the tunnel. Like someone briefly struck a match. Then nothing. I shouted Hello, are you in there? A pause. Then a single sharp sound answered me from the dark. Someone flickin' a lighter. I walked deeper and slowly. My torchlight shook. Every twenty steps or so I heard another click far ahead. Then closer a click. Someone opening and closing a lighter, but never lighting it. The air grew colder the further I went in. My breath floated in front of me. On the ground I saw footprints in the dust, one set deep and fresh. They laid forward towards the clicks, probably the missing walker. I followed them, then I saw something that made me stop dead. The footprint suddenly turned to the right, straight into the tunnel wall. No smear, no slide, just a clean stop, as if the person walked into the wall and vanished. I backed up. My chest tightened. Then a click right next to my ear. I spun around, torch sweeping, nothing behind me, nothing beside me. But the wall next to my torch had a scorch mark, a small burn mark, the size of a foam. Like someone held a flame to the brick moments before I turned. I kept walking because something inside me said the missing walker might still be alive, but the further I went, the more the tunnel changed. The air got thick and hard to breathe. The wall seemed too narrow. Then a whisper drifted from ahead, soft shaking. Please don't come closer. My blood ran cold. It wasn't a shout, not a warning. It sounded like someone who had given up. Hello? I called. Where are you? No. The whisper breathed got. Go back. It waits. I felt my whole body start to tremble. What waits? I whispered. Silence. Then the loudest click yet, sharp and violent, echoed so close it felt like it was right in front of my face. My torch flickered just once, and when the beam steadied, the tunnel ahead was different. There was someone standing in the dark. He stood sideways, facing the brick wall, not moving. At first I thought his clothes were torn, but then I realized I wasn't seeing clothes. I was seeing skin. Grey, stretched, cracked like old plaster. The figure's head was down chin to chest, like he was listening for something under his feet. I whispered Sir The figure slowly lifted one arm, not towards me, but sideways, raising a small metal object. A lighter. He flicked it. Click, no flame. This time, when he flicked it again, I saw something behind him, a shape peeling itself out of the darkness on the wall. Long arms and longer legs. A body bent the wrong way, like a spider trying to stand upright. Its skin looked burned, blackened, shiny in places, and where its face should have been, there was only a mouth, wide open, and stretched across half its head. It dropped from the wall without a sound. The figure with the lighter didn't react. It didn't move, didn't even turn. I whispered We need to go now. But the man didn't answer. The thing behind him did in his exact voice go now. Then it smiled a long, sharp smile. That didn't match any human shape. My torch flickered again as the creature stepped into the edge of the beam. He had no eyes, just that giant mouth, teeth long and thin like nails. It lifted one long arm, reached for me, and the man with the lighter finally moved. He stepped in front of the creature. Lighter raised as if shielding me. He whispered please run. Then the lighter clicked one last time, click, and this time it lit. A tiny flame orange and shaking. For a split second the whole tunnel lit up, walls dust, and the full shape of the creature behind him. It was enormous. Too tall, arms like ropes, skin melted and hanging, and that mouth opened wide enough to swallow a man whole. The flame blew out. Darkness swallowed everything. I ran. I didn't look back, I didn't slow down. I followed the faint glow from a dying torch until I burst through the tunnel entrance and fell onto the wet grass outside. Beside me, deep in the black, I heard one last sound. Click, then nothing. The missing walker was never found. Not a bone, not a boot, nothing. Only the scorch mark on the wall remained. Fresh and dark. Right where I had heard that first click. I still don't know what weighted down there and what it wanted, or why the man, the one who looked half dead already, tried to protect me. But I'll tell you this, if you ever find yourself near a World War II tunnel and you ever hear a light a clicking in the dark, don't wait for a flame. The moment it lights, it's already too late. The deeper you go underground, the more the world changes. Light fades, sound shifts, and the dark stops being empty. Tonight we've walked through places built by miners, soldiers, explorers, and places built by something else entirely. Tunnels where voices copy you, mines where shadows move on their own, and water where hands rise to knock from below. Down there, rules don't matter, maps don't matter. And once something knows you're in its world, it doesn't forget. If you've had an unexplained experience of your own and would like to share it, you can visit realunexplained stories.com.
