The hospital had thirteen rooms, but every night at 2:13 a fourteenth door appeared.

No one admitted seeing it until the night something knocked from the other side.

Nurse Elena Ward had worked nights for six years, but nothing in her training explained why the knocking knew her name.

She told herself it was a prank until the voice behind the door sounded exactly like her mother.

Her mother had been dead for eleven years.

Elena reached for the handle, but someone grabbed her wrist before she could touch it.

The old patient from Room 7 stared at her and whispered that opening the door was exactly what it wanted.

Elena asked what he meant, but his answer made her wish she hadn’t.

He said the door had appeared in another hospital thirty years earlier.

That hospital no longer existed.

According to him, neither did most of the people who had worked there.

Elena laughed nervously until he told her something he couldn’t possibly know.

He knew what her mother had said before she died.

Elena demanded an explanation, but the lights went out before he could give one.

When the emergency lights flickered on, the old man’s bed was empty.

His blanket was still warm.

The monitor beside the bed continued displaying a heartbeat.

Elena called security, but they insisted nobody had been admitted to Room 7.

She opened the electronic chart and found something worse.

Room 7 had supposedly been empty for three months.

Then the knocking started again.

This time it came from inside Room 7.

Elena backed toward the hallway as a voice whispered from beneath the bed.

It was the old man.

He told her not to look underneath.

Something scratched against the floorboards.

Elena ran before curiosity could overpower fear.

At the nurses’ station, she discovered every security camera had frozen at exactly 2:13.

Except one.

The camera facing the mysterious door was still recording.

Elena clicked the feed and saw herself standing in front of it.

The problem was that she was currently twenty feet away.

The Elena on the screen slowly turned toward the camera.

Then she smiled.

Elena wasn’t smiling.

The woman on the monitor raised one finger to her lips.

Then the feed went black.

Elena grabbed her phone, but there was already a message waiting.

It had been sent from her own number.

The message contained only four words.

You already opened it.

Elena dropped the phone.

Behind her, the elevator chimed.

The doors opened onto a hallway that shouldn’t have existed.

Every room along it had her name written beside the door.

One said ELENA — AGE 8.

Another said ELENA — AGE 17.

The final room said ELENA — TONIGHT.

She pressed the elevator-close button, but nothing happened.

Then she heard a child crying from the first room.

Elena recognized the crying immediately.

It was her own.

She stepped into the impossible hallway despite every instinct telling her not to.

The elevator doors closed behind her.

Her phone suddenly regained service.

There were forty-seven missed calls.

Every call was from tomorrow.

She answered the newest voicemail.

Her own voice begged her not to enter the last room.

Then the recording ended with a scream.

Elena turned around.

The elevator was gone.

Only the hallway remained.

The door marked AGE 8 creaked open.

Inside was her childhood bedroom exactly as she remembered it.

Her younger self sat on the bed staring into the closet.

Elena remembered this night.

It was the night she first told her mother there was a man inside the closet.

Her mother had convinced her it was only a nightmare.

But now Elena could see that someone really was standing inside.

The figure stepped forward.

It was the old patient from Room 7.

He looked thirty years younger.

He whispered that Elena had finally remembered him.

She didn’t.

Then he told her his name.

Daniel Ward.

Elena stopped breathing.

That had been her father’s name.

Her father had supposedly died before she was born.

Daniel told her that was the first lie.

The second lie was worse.

Elena had not been eight years old when she first saw the door.

She had been eight years old when she first opened it.

The bedroom disappeared.

Elena was suddenly standing inside an operating room.

A surgeon leaned over a small child on the table.

The child was Elena.

But the surgeon wasn’t performing surgery.

He was removing something that moved beneath her ribs.

Elena screamed for him to stop.

The surgeon looked directly at her.

He had no face.

The thing beneath young Elena’s ribs suddenly stopped moving.

Then Elena felt something move beneath her own.

She stumbled backward.

The operating room vanished.

She was standing before the final door.

ELENA — TONIGHT.

Her future voice screamed from behind it.

She refused to open it.

The handle turned anyway.

Inside, Elena saw the hospital nurses’ station.

Her coworkers were laughing and charting as if nothing had happened.

Elena nearly cried with relief.

Then she noticed herself sitting among them.

The other Elena looked perfectly normal.

Until she turned around.

Her smile was too wide.

Elena tried to warn everyone, but nobody could hear her.

The other Elena stood and walked toward the supply room.

A young nurse followed her inside.

The door closed.

A scream followed.

Elena slammed against the invisible barrier separating them.

The fake Elena emerged alone.

Nobody noticed the blood on her hands.

Then another nurse followed her.

And another.

Elena finally understood what the mysterious door actually was.

It wasn’t trying to get inside the hospital.

It was trying to get outside.

And it had chosen her face to do it.

Elena searched desperately for another exit.

That’s when she noticed the old patient standing behind her.

Daniel said there was one way to stop it.

But Elena would have to remain behind the door forever.

She asked what would happen if she refused.

Daniel pointed through the window.

The fake Elena was already walking toward the hospital entrance.

Sunrise was approaching.

Patients would soon fill the waiting room.

Then the thing wearing Elena’s face would have hundreds of choices.

Elena asked Daniel why he couldn’t stop it himself.

His expression answered before his words did.

He had once made the same choice.

Thirty years ago, Daniel had stayed behind the door.

But someone eventually replaced him.

That someone had been Elena.

She finally remembered her mother standing beside the strange door when Elena was eight.

She remembered being told never to touch the handle.

She remembered touching it anyway.

And she remembered Daniel pushing her back through.

The effort had allowed something else to escape.

Her mother had spent the rest of her life hiding the truth.

Now the cycle had returned for Elena.

The hallway began collapsing behind them.

The fake Elena reached the hospital’s front doors.

Elena had seconds to decide.

She grabbed Daniel’s hand.

Then she stepped backward into the darkness.

The fake Elena froze.

Its head snapped toward the security camera.

Its smile disappeared.

Then its body folded inward like an empty uniform.

Elena opened her eyes.

She was standing behind the mysterious fourteenth door.

Daniel was gone.

The hospital continued normally on the other side.

Nobody remembered Elena had ever worked there.

Weeks passed.

Then months.

Elena stopped counting.

Occasionally someone walked past the door without seeing it.

Occasionally someone almost did.

Then one night, at exactly 2:13, a new nurse stopped in the hallway.

The nurse stared directly at Elena’s door.

Elena backed away.

The nurse stepped closer.

Elena screamed at her not to touch it.

The nurse couldn’t hear her.

Then something behind Elena whispered her name.

She turned around.

There was another door.

She had never seen it before.

Three words were written across its surface.

DO NOT OPEN.

Something knocked from the other side.

Then Elena heard her daughter’s voice.

And the handle began to turn.
