A lot of people remember their dreams for a few minutes after waking up and then forget them forever.
I used to be one of those people.
Until the morning someone described my dream to me in perfect detail.
It happened during a period when I was living alone in a rented apartment on the edge of the city. The building wasn’t old, but it wasn’t exactly new either. Most tenants kept to themselves. I worked late shifts at a warehouse and usually returned home after midnight.

The dream started appearing every few nights. Nightmare Horror Story
In it, I would walk through a narrow corridor lined with dozens of closed doors. The corridor seemed endless. The walls were stained with dark patches that looked like water damage. At the far end stood a man wearing a long gray coat. I could never see his face clearly.
Every time I tried to approach him, he would slowly raise one hand and point toward a specific door.
Door Number 17.
The dream always ended before I reached it.
At first, I ignored it.
People have strange dreams all the time.
But after seeing the same dream five times in two weeks, it started bothering me.
The details became more vivid with every appearance. I could hear the faint buzzing of fluorescent lights above me. I could smell damp wood. Sometimes I thought I could even feel the cold air of the corridor after waking up.
One Friday morning, after another night with the same dream, I stopped at a small tea stall near the warehouse before heading home.
A few customers stood around drinking tea and checking their phones.
I ordered a cup and waited.
That’s when a stranger approached.
He looked ordinary enough. Mid-forties. Thin build. Dark jacket. Nothing memorable about him except his eyes.
They seemed unusually focused.
He stopped beside me and asked, “Did you open the seventeenth door yet?”
I laughed awkwardly.
“Sorry?”
“The corridor,” he said calmly. “The man in the gray coat keeps pointing toward Door Seventeen. You never reach it.”
The cup nearly slipped from my hand.
For a moment I genuinely thought he was joking.
Maybe someone I knew had told him something.
Maybe he was playing a prank.
But nobody knew about that dream.
I had never mentioned it to anyone.
The stranger smiled slightly.
“You should stop walking down that hallway.”
Then he turned and walked away.
I stood frozen.
By the time I recovered enough to follow him, he had disappeared into the morning crowd.
The encounter haunted me all day.
I barely slept that night.
When I finally drifted off, the dream returned.
This time something was different.
The corridor seemed darker.
The fluorescent lights flickered constantly.
The man in the gray coat wasn’t standing at the far end anymore.
He was much closer.
Close enough for me to notice his face.
Or at least part of it.
His skin looked pale and stretched tight, almost like wax.
His eyes appeared completely black.
When he pointed toward Door 17, his arm bent at an unnatural angle.
Nightmare Horror Story
Then he spoke for the first time.
“Someone is watching.”
I woke up gasping.
The digital clock beside my bed showed 3:13 AM.
The room felt unusually cold.
Then I noticed something that made my stomach twist.
My bedroom door was slightly open.
I always locked it before sleeping.
Always.
I got up, checked the apartment, and found nothing unusual.
No signs of entry.
No missing belongings.
Nothing.
Yet I couldn’t shake the feeling that someone had been standing inside my room while I slept.
Over the next week, strange things started happening.
Small things at first.
Objects moved slightly from where I left them.
Kitchen cabinets opened by themselves.
I began hearing footsteps in the hallway outside my apartment around 3 AM every night.
The footsteps would stop directly outside my door.
Then silence.
No knocking.
No voices.
Just silence.
One night I looked through the peephole.
The hallway was empty.
But the footsteps continued.
Slow.
Deliberate.
As if someone invisible was pacing back and forth.
Sleep became impossible.
Every time I closed my eyes, I feared returning to the corridor.
Eventually curiosity overcame fear.
I wanted answers.
So the next time the dream appeared, I forced myself to walk faster.
The gray-coated figure remained motionless as I approached.
Door 17 waited at the end of the hallway.
For the first time, I reached it.
The door was old and covered with scratches.
Hundreds of them.
As if countless people had clawed at it from the other side.
My hand reached for the knob.
The figure suddenly whispered:
“Don’t let him know you found it.”
Before I could ask who he meant, the door opened by itself.
Darkness filled the doorway.
A darkness so deep it seemed alive.
Then something moved inside.
A silhouette.
Tall.
Thin.
Watching me.
I woke instantly.
The room was silent.
But something had changed.
The dream felt less like a dream now.
More like a memory.
The next afternoon, while leaving work, I saw the stranger again.
He stood across the street near a bus stop.
Waiting.
As if he knew I’d be there.
I crossed immediately.
“Who are you?” I demanded.
“Someone who made the same mistake.”
His expression was completely serious.
“What mistake?”
He looked around before answering.
“I opened the door.”
A chill ran through me.
He continued.
“Years ago I started dreaming about that hallway too. Eventually I reached Door 17. After that, it stopped being a dream.”
“What does that mean?”
“It learns about you.”
The answer sounded insane.
Yet something in his voice felt genuine.
He looked exhausted.
Like a man who hadn’t slept properly in years.
“The more attention you give it, the stronger it becomes.”
“What becomes stronger?”
The stranger hesitated.
Then he said quietly:
“The thing behind the door.”
Before I could ask more questions, a bus pulled up between us.
Passengers stepped out.
For only a few seconds he disappeared from view.
When the bus moved away…
He was gone.
Not walking away.
Not crossing the street.
Gone.
As if he had never been there.
That night I didn’t sleep at all.
I kept every light in the apartment turned on.
Around 3:13 AM, the footsteps returned.
Slow.
Measured.
Outside my door.
Then they stopped.
A soft scratching sound followed.
Scrape.
Scrape.
Scrape.
I approached the peephole.
The hallway appeared empty again.
Then the scratching stopped.
For several seconds there was complete silence.
Suddenly a face appeared inches from the peephole.
Not a human face.
A pale shape with black eyes.
Watching directly into mine.
I stumbled backward in terror.
The apartment lights flickered.
When I looked again, the hallway was empty.
The next morning I found scratches carved into my front door.
Seventeen of them.
Perfectly parallel.
That was the moment I decided to move.
Within two weeks I relocated to another city.
Different apartment.
Different job.
Different life.
For a while, things seemed normal.
The dreams stopped.
The footsteps stopped.
The fear slowly faded.
I convinced myself the entire experience had been stress and sleep deprivation.
Until six months later.
One evening I entered a crowded supermarket after work.
As I pushed my cart down an aisle, I noticed an elderly woman staring at me.
Not glancing.
Staring.
When our eyes met, she smiled sadly.
Then she said:
“You found Door 17.”
My blood turned cold.
The woman leaned closer.
“He knows where you are now.”
Before I could respond, she walked away.
I searched the entire store.
She had vanished.
That night I dreamed of the corridor again.
Only this time there was no gray-coated figure.
No distant hallway.
No Door 17.
I was already standing inside the room beyond it.
And something was standing behind me.
Breathing.
Waiting.
When I woke up, there was a message written across the fogged bathroom mirror.
Five words.
Words I still see in my nightmares.
YOU SHOULD HAVE KEPT WALKING.
