It’s the 13th in October—prime time for eerie ideas. Whether you’re drafting flash fiction or a longer tale, these prompts bring atmospheric chills, uncanny imagery, and deliciously unsettling twists. Pick one and run with it tonight. 💀🕯️
Writing Prompts
- The Thirteenth Knock
Every night at 1:13 a.m., someone knocks exactly thirteen times on your door. You finally open it—only to find a handwritten note addressed to your future self… in your own handwriting. - Harvest of Names
A rural town ties ribbons around a scarecrow every autumn, each ribbon inscribed with a resident’s name. On October 13th, the ribbons begin untying themselves—one by one. - The Candle That Wouldn’t Go Out
You inherit a black candle that never burns down. It reveals whispers when the flame gutters—whispers that know what you did last Halloween. - Room 1313
Your hotel has no 13th floor, yet the elevator stops there anyway. The doors open to a corridor filled with framed photos of you sleeping… from ages you don’t remember. - A Borrowed Shadow
Your reflection looks normal, but your shadow belongs to someone else. On October 13th, the shadow starts pointing at places you’ve never been—and things you never should have seen. - Pumpkin King’s Tithe
Local legend says the pumpkin patch chooses one “keeper” every thirteen years. This season, all the vines have crawled to your front step, spelling your name in dirt. - Thirteen Seconds of Silence
At exactly 13:13 on 10/13, every device goes silent worldwide for thirteen seconds. In that hush, a message arrives that only you can hear: a countdown and a choice. - The Librarian After Hours
You’re cataloging a donation box labeled “1313.” Each book’s margins contain notes from a previous reader begging you not to turn the next page. You turn it anyway. - The Bone Bridge
A fog reveals a bridge that exists only on October 13th. Crossing it takes thirteen steps. On the fourteenth, you realize the footsteps behind you aren’t echoes. - Witch’s Ledger
You discover a leather-bound account book listing debts owed to a witch—debts paid in memories. There’s one entry left unpaid: yours, dated thirteen years ago. - The Mask That Fits Too Well
At a thrift shop, you find a porcelain mask labeled “For One Night Only.” When you put it on, your heartbeat syncs with someone—or something—else hunting in the dark. - Thirteen Chairs
You’re invited to a midnight séance with twelve strangers. The medium says the thirteenth chair is for the one who arrives late. The door knocks—inside the circle. - Graveyard Frequency
Your old radio only gets one station on October 13th, playing dedications from the dead to the living. Tonight, a familiar voice requests your favorite song—and gives you instructions.
How to Use These Prompts (Quick Tips)
- Set a timer (13–30 minutes). Draft fast, revise later.
- Pick a constraint. First-person present, under 1,300 words, or only candlelit settings.
- Add a twist. Turn the apparent “monster” into the protector—or the narrator into the threat.
- Layer the senses. Let readers smell damp leaves, feel wax drips, hear distant chimes at 1:13 a.m.
Optional Micro-Challenges
- Include three seasonal images (fog, brittle leaves, a cracked mirror).
- Use exactly thirteen paragraphs.
- End with a choice (open ending with consequence).
If you want, I can turn your favorite prompt into a full beat sheet or a 1,300-word outline for NaNoWriMo prep. 🎃
Happy Writing ^_^
