Mara entered the hospital for a routine sleep study after months of waking with bruises she could not explain. The cameras showed that she never left her bed, but another patient appeared beside her every night at 3:17. The hospital had no bed with the number shown on his wrist.

Chapter 1: The Visitor at 3:17

Mara hated sleeping where strangers could watch her.

The technician had placed small sensors across her scalp, chest, and legs. Wires ran from her body to a box beside the bed. A camera watched from the ceiling.

“It records movement, breathing, oxygen, heart rhythm, everything,” the technician explained. “Just sleep normally.”

Mara almost laughed. Nothing about this was normal.

For three months, she had awakened with bruises around her wrists and ankles. Sometimes dirt covered her feet. Once, she found a hospital bracelet beneath her pillow.

It carried her name and birthday.

The admission date was six years earlier.

Mara had never been admitted to this hospital.

Her doctor blamed sleepwalking. That was why she had agreed to the overnight study.

At 10:40 p.m., the technician turned off the lights.

Mara stared into the dark until sleep finally took her.

She awoke to someone breathing beside her.

The room remained dark, but a shape sat in the visitor’s chair. It looked like a thin man wearing a hospital gown.

“Are you the nurse?” Mara whispered.

The man lifted one finger to his lips.

The monitor beside her began chiming. Her oxygen level had fallen from 98 to 76.

Mara tried to call for help, but her body would not move.

The man stood.

A plastic wristband circled his arm.

BED 0.

He leaned over Mara and pressed his mouth close to her ear.

“Don’t let them wake you.”

The door opened. Light filled the room, and two technicians rushed inside.

Mara could move again.

The chair was empty.

During the first night of Mara’s sleep study, her oxygen suddenly fell while a man wearing a Bed Zero bracelet appeared beside her. The staff saw no visitor, but the recording equipment captured something they could not explain.

Chapter 2: A Death Record With Her Name

In the morning, Dr. Havel reviewed the video.

Mara watched herself sleeping beneath the blanket. At 3:17 a.m., her chest stopped moving.

Then the visitor’s chair turned toward the bed.

No one touched it.

A dark shape formed in the seat. It had shoulders, arms, and a head, but no face.

The shape stood and leaned over Mara.

Her breathing returned.

“That thing didn’t hurt me,” Mara said. “It made me breathe.”

Dr. Havel paused the video.

For one frame, a white bracelet showed against the shadow’s wrist.

BED 0.

“There is no Bed Zero,” he said.

The hospital’s sleep unit contained eight rooms, numbered one through eight. It had opened twelve years earlier.

Mara showed him the bracelet she had found at home. The plastic was yellow with age, but its printed letters remained clear.

MARA VOSS

ADMITTED: OCTOBER 14

Today was October 14.

Dr. Havel’s face changed.

“Where did you get this?”

“Under my pillow.”

He placed it in a specimen bag.

Mara expected to go home, but her results showed severe pauses in her breathing. One lasted eighty-three seconds. Dr. Havel recommended another night of monitoring while they arranged a breathing machine.

That evening, Mara called her mother.

At first, her mother said nothing about the old bracelet. Then Mara read the date aloud.

Her mother began crying.

Six years earlier, Mara had been found unconscious in her apartment. A faulty heater had filled the building with carbon monoxide, an invisible gas that blocked oxygen from reaching the body.

Three people died.

Mara remembered none of it.

“You were taken to St. Vincent’s old emergency wing,” her mother said. “They ran out of beds. They put you on a stretcher in the hallway.”

“What bed number?”

“It didn’t have one.”

A male nurse stayed beside Mara for hours, squeezing air into her lungs whenever she stopped breathing. He kept her alive until she could be transferred.

“What was his name?” Mara asked.

“I don’t know. He died that same night.”

Mara looked toward the empty visitor’s chair.

A faint dent slowly appeared in its cushion.

The mysterious figure had once kept Mara breathing during a carbon-monoxide disaster she could no longer remember. Six years later, on the same date, he had returned as her breathing began to fail again.

Chapter 3: Discharge Pending

At 3:10 a.m., Mara was still awake.

The breathing machine covered her nose and pushed air into her lungs. Dr. Havel watched from the control room.

At 3:17, the machine stopped.

The screen went black. The lights died. Even the battery-powered monitor shut off.

The door would not open.

Mara pulled at the mask, but its straps tightened around her head. No air came through the tube.

The visitor’s chair turned.

The man appeared.

This time, Mara saw burns covering one side of his body. His hospital gown was black with smoke.

He pointed beneath her bed.

Mara reached down and found another breathing tube hidden under the frame. It was old, cracked, and stained brown. Yet air pulsed from its open end.

She connected it to her mask.

Cold air filled her lungs.

The door burst open seconds later. Dr. Havel entered with a flashlight.

Power returned.

The figure vanished.

Mara told him about the tube. They searched under the bed, but found nothing.

A maintenance worker later discovered that the machine had been deliberately unplugged from the wall. The backup battery had also been removed.

Security footage showed no one entering the room.

Mara left the hospital the next morning with a new breathing machine. Her oxygen remained normal at home, and the unexplained bruises stopped.

She thought Bed Zero had finally released her.

One week later, Dr. Havel called.

The hospital had identified the nurse from the old emergency wing. His name was Samuel Orr. During the carbon-monoxide disaster, he had helped six patients breathe by hand.

Only five survived.

Mara was not one of the five.

According to the official death record, Mara Voss had been declared dead at 3:17 a.m.

Her mother had identified the body.

“That’s impossible,” Mara said.

“I know,” Dr. Havel replied. “But there’s something else.”

The sleep-lab camera had recorded one final image after Mara left.

The bed was empty.

Samuel stood beside it, facing the camera.

Someone lay beneath the blanket.

Dr. Havel enlarged the patient’s wristband.

DISCHARGE: PENDING

That night, Mara awoke unable to breathe.

Samuel sat beside her.

But this time, he did not reach for the breathing machine.

He looked toward the bedroom door.

Another Mara stood there, wearing a hospital gown.

And she was waiting for her bed.
