31 Days of Horror: The Horror Of Forever - Short Stories That Address the Nightmare of Eternity

Horror isn’t just a genre; it’s an amalgamation of pop culture, cozy traditions, and things that go bump in the night. This year, we're taking our 31 Days of Horror across the entire cultural spectrum. We’ll be taking a look at movies that scare us, games that kept us paranoid, scary books we cozy up with under blankets, music that sets that spooky tone and seasonal food we’re craving–or strange food you’d have to tie us up and force feed us. Whether you’re looking for something truly terrifying or a cozy autumn haunt, come back every day this month for a new bite-sized review or spooky adjacent list.

Freddie Mercury probably said it best: “Who wants to live forever?”

Okay, I’m being facetious. But when contemplating eternity, I feel a deep existential despair. To experience eternity, to live forever. It’s enticing in its way. But truly forever can be a prison, and a nightmare unto itself. When horror is discussed, it’s often in terms of monsters and slashers: the creature in the dark or the killer stalking you in the woods. The final snap at the end of a rope. These terrify us because of the finality. But what if there was no end? 

The human mind is like a finite vessel: it can be filled up. Eternity is too large to grasp. The infinite can only be discovered through finite terms. Given enough time, survival and eternal life might turn into a punishing nightmare. To help kickstart your descent into the horrible different types of eternities, I’m looking at 9 stories that have their own take on what forever can mean. 

Part I: The Cosmic Weight

Douglas Adams insisted that space is large, but even then we’re considering it on the scale of the solar system or a Galaxy. And even these distances pale in comparison to true infinity. These stories establish the argument that infinite space and time inevitability strip away humanity

• "The Immortal" by Jorge Luis Borges

  
  

Borges is not a horror author–more of a philosopher and a scholar. That’s what makes his works so acutely terrifying to me: a mind that is capable of vast thought, still struggling under the weight of forever. “The Immortal” is about a man who seeks out physical immortality, and gets it, only to discover its terrible price: infinite time renders every action, thought and achievement meaningless, leaving existence a stagnant, featureless blur. It’s a great story that allows you, the reader, to come to these realizations along with its protagonist.

• "The Aleph" by Jorge Luis Borges

Borges uses himself as a main character in this story of seeing into infinity. Instead of infinite time, he ponders infinite space—and the devastating effect it can have on those who perceive it. The true horror here is the sheer, crushing weight of infinite information collapsing onto a human mind that is simply unable to process it all.

• "The Last Question" by Isaac Asimov

“Can entropy be reversed?” is the question asked in this classic Asimov short story. It tracks the terrifying inevitability of a dying universe. Even a supercomputer that spans galaxies and exists for trillions of years can only answer “insufficient data for meaningful answer” as humanity watches the stars slowly fade and die.

Part II: The Architecture of Infinity

Eternity is represented here by an actual place. In both of these stories. Borges’ LIbrary of Babel is first introduced by the philosophical Borges, but then that abstract location is the setting of Peck’s short story–with a few tweaks to make the bleak reality of forever linger in your mind.

• "The Library of Babel" by Jorge Luis Borges

Here, eternity is represented through physical space and infinite information. Borges describes an endless library containing every possible combination of letters. The sheer, unfathomable volume of meaningless data crushes the human spirit in this short story, which serves as a dark allegory for humanity’s quest for knowledge and truth.

There can never truly be an end to the search, and those who try to touch the edges of infinity will either die trying, or be driven to absolute madness.

• "A Short Stay in Hell" by Steven L. Peck

This is a direct, terrifying successor to the Library of Babel. It takes Borges' abstract dread and grounds it with rules, forcing a relatable human protagonist to actually walk those endless halls.

To escape this vision of hell, he must find the exact book containing his life's story within a mind-bendingly vast, almost infinite collection. When the actual number of books is finally revealed, the figure is so massive as to be completely meaningless. Peck doesn’t leave readers with a satisfying conclusion, driving home the ultimate horror: the quest for absolute truth far exceeds our mortal ability to endure it.

Part III: The Prison of Consciousness

This is where the concept plummets into pure horror, both psychological and physical, included some body horror thrown in for fun. Eternity is no longer just a setting; it becomes an active, hostile force.

• "The Jaunt" by Stephen King

We’ve all had that debate about Star Trek transporters—you know the one I’m talking about. But what if you remove the philosophical debate about who is coming out the other side, and instead focus on what exists between those two points?

In “The Jaunt,” King explores the terror of pure, bodiless consciousness. The story is framed as a father recounting the history of teleportation to his family right before they take their first “jaunt,” assuring them that the process is perfectly safe. But this being a Stephen King story, you know it’s anything but. 

• "I Have No Mouth, and I Must Scream" by Harlan Ellison

What if you take the supercomputer from Asimov’s story and made it an insane malevolent entity that hated humanity? Ellison created a nightmare story where the last humans are forced to live forever, only to suffer for all of humanity’s transgressions.

Being kept alive by an omnipotent, hateful AI that can alter your body and mind to prolong suffering is a type of hell that makes nightmares. Also adapted into a point-and-click adventure game that is just as miserable to play as the poor humans that have to endure the malicious AM.

• "Divided by Infinity" by Robert Charles Wilson

Wilson takes the thought experiment of “quantum immortality” and lets it play out to its bleakest conclusion.

It turns out, surviving every deadly scenario creates a world full of strange probabilities and branching realities. The idea is that consciousness, like energy, cannot be destroyed. Instead, the universe simply won’t let the protagonist die, forcing him to survive into increasingly alien and terrifying versions of reality. Not to mention, surviving forever ultimately means outlasting everyone you have ever known or loved.

Part IV: The Catharsis

This story is a complete palate cleanser. Here, Weir (known for Project Hail Mary, The Martian) looks at infinity and reframes it entirely.

• "The Egg" by Andy Weir

This is a story I originally read on a message board years ago. It randomly popped into my head recently, and I was delighted to discover the author was Andy Weir—long before he was stranding astronauts on Mars or sending them on desperate interstellar survival missions in Project Hail Mary, which are works I’ve come to absolutely adore.

After all the existential dread we've just waded through, this story asks a different question: what if infinity wasn’t a hellish prison, but a sort of gestational period? I don’t want to spoil too much, but it's the perfect, beautiful palate cleanser to end our descent into forever.
