Threshold Event
The staff remained perfectly still outside the lounge windows.
Smiling.
Not naturally.
Their expressions stretched too wide across motionless faces while the hallway lights flickered softly above them. Doctors. Security personnel. Technicians. Every employee visible through the glass stood frozen in the exact position where they had stopped moving seconds earlier.
Watching the participants.
Watching Ethan.
Dr. Evelyn Mercer backed slowly away from the lounge entrance, her calm professional mask finally beginning to crack.
“They shouldn’t be awake yet.”
The sentence sent cold silence through the room.
Daniel Cross looked toward her sharply. “Who?”
Nobody answered immediately.
Then one of the frozen staff members outside twitched violently.
A sharp unnatural jerk of the neck.
Another employee copied the movement.
Then another.
Like invisible strings pulling all of them simultaneously.
Leah started crying again immediately. Mira physically grabbed Ethan’s arm tighter while the smiling figures beyond the glass began moving together in slow synchronized motions.
Step.
Step.
Step.
Every employee in the hallway started walking toward the lounge doors at the exact same pace.
Dr. Mercer whispered something under her breath.
“Containment failed…”
Ethan looked toward her instantly. “What are they?”
The doctor stared at the approaching staff with visible horror before finally answering.
“They crossed the Threshold.”
The employees stopped directly outside the automatic lounge doors.
Dozens of them now.
Still smiling.
Still silent.
Then one of the security guards slowly lifted his hand toward the glass.
And knocked.
Knock.
Knock.
Knock.
Every person inside the lounge flinched simultaneously.
The guard tilted his head sideways unnaturally afterward while speaking through the glass.
Not loudly.
Almost gently.
“You’re still dreaming.”
Daniel backed away immediately. “Nope.”
Then all the staff outside began knocking together.
Knock.
Knock.
Knock.
The sound echoed violently through the lounge like a ritual rhythm spreading across the walls and floor beneath them.
Dr. Mercer rushed toward a security panel beside the doors and slammed her access badge against it repeatedly.
Nothing happened.
The system remained dead.
“They disabled internal controls,” she muttered.
Ethan stared at the smiling employees outside. “How?”
Dr. Mercer finally looked directly at him.
“Because they aren’t fully human anymore.”
Silence hit the room.
Nobody even tried denying it this time.
Not after everything they’d already seen.
The knocking outside intensified harder.
Then the smiling employees stopped simultaneously again.
Complete stillness returned.
And one of the technicians pressed her face slowly against the glass.
Her eyes looked wrong.
Not white.
Empty.
Like depthless black pupils swallowing the entire iris.
Then she whispered softly through the glass:
“Aaron is waiting downstairs.”
Ethan’s stomach tightened instantly.
His father.
Or whatever remained of him after nineteen years inside Somna Labs.
Dr. Mercer grabbed Ethan’s wrist suddenly.
“You cannot go below Sector C.”
The urgency in her voice sounded completely genuine now.
Ethan stared at her. “You brought me here because of him.”
“Because he’s connected to the Threshold event.”
“What does that even mean?”
Dr. Mercer hesitated.
The knocking outside resumed again.
Harder now.
The glass walls trembled slightly beneath repeated impacts from the smiling staff members.
Finally the doctor answered.
“The original experiment was supposed to study sleep deprivation.” Her breathing shook slightly. “But during the Ninth Night, participants began reporting identical hallucinations.” She looked toward the floor beneath them. “Then they started sharing memories.”
Mira frowned in confusion. “Sharing?”
“They remembered things that happened to other participants. Dreams. Childhood memories. Conversations they never had.” Dr. Mercer’s voice lowered further. “The boundary between individual consciousness began collapsing.”
The room fell silent except for the violent knocking outside.
Ethan slowly understood.
“Threshold Theory.”
Dr. Mercer nodded once.
“The brain normally separates internal perception from external reality.” She swallowed visibly. “Extreme sleep deprivation weakens that separation.”
Leah whispered shakily, “That’s impossible.”
“Yes,” Dr. Mercer agreed immediately. “It should be.”
Then a loud crack split across the lounge doors.
Everyone jumped.
The glass had begun fracturing beneath the impacts from outside.
The smiling employees continued knocking in perfect rhythm without reacting to the damage at all.
Knock.
Knock.
Knock.
Another crack spread through the glass.
Daniel stepped backward toward the stairwell door. “We need another exit.”
“There isn’t one,” Dr. Mercer answered.
The words landed heavily.
Then Ethan remembered something.
“The access elevator.”
Dr. Mercer’s expression changed instantly.
“What?”
“The man from the van said there’s an elevator near Sector D.”
For the first time since entering the lounge, genuine hope flickered across Daniel’s face.
But Dr. Mercer looked horrified instead.
“No.”
“Why?”
“Because Sector D connects to the Ninth Floor.”
Silence.
Mira slowly shook her head. “You keep saying Ninth Floor even though this place only has six levels.”
Dr. Mercer looked toward the shaking lounge doors.
Then finally whispered:
“Not anymore.”
Another violent impact shattered part of the glass.
A security guard outside slammed his head repeatedly against the doors while smiling wider with every hit. Blood spread down the fractured surface.
Yet he never stopped smiling.
The other staff members copied him instantly.
Bang.
Bang.
Bang.
The doors began buckling inward.
Dr. Mercer grabbed a flashlight from the emergency cabinet beside the wall.
“If they reach us while the Threshold is active,” she whispered urgently, “they’ll pull you into shared cognition.”
Daniel blinked once. “English.”
Her eyes locked onto his.
“You’ll stop knowing which thoughts belong to you.”
Nobody spoke after that.
Because suddenly the smiling people outside the lounge looked far more terrifying than monsters.
Then the doors finally shattered inward.
And the staff rushed inside together.
