70 Horror Creative Writing Prompts for Teens: Story Starters, Titles, Characters, Settings & Visual Ideas

Horror writing isn’t just about jump scares and ghosts, it’s about tension, unease, and what’s left unsaid. It’s one of the most effective genres for teaching atmosphere and voice, and it gives students the chance to explore fear in a way that feels safe and creative. These horror writing prompts are designed for teen writers and include story ideas, titles, eerie opening and closing lines, character concepts, unsettling settings, and image-based inspiration. Whether you're building a whole unit or just want a no-prep creative task, there's something here to get under their skin.

1. Plot Hooks

These horror story prompts are built for slow dread, strange happenings, and the kind of fear that lingers. Some are paranormal. Some are psychological. All of them leave space for the unknown, and for students to build a narrative around what might be hiding just out of sight:

1. Write a story about a letter you wrote last year that’s finally answered, but not by the person you sent it to.

2. Write a story about something knocking on your window every night at the same time, even though you live on the 14th floor.

3. Write a story about somebody who goes missing during a class trip, but when they come back, they are wearing different clothes and calling you by the wrong name.

4. Write a story about a family rule you’ve followed your whole life, and then one night you decide to break it.

5. Write a story about your childhood imaginary friend, who just left you a voicemail.

6. Write a story about a school trip that shows somebody who wasn’t there.

7. Write a story about waking up to find a handwritten note under your pillow that simply says: “Don’t look in the mirror”.

8. Write a story about a small location tradition nobody talks about, until you refuse to participate.

9. Write a story about a door that appears in your house, but it wasn’t there yesterday and won’t open today.

10. Write a story about a playlist on your phone that you don’t remember downloading, but every song is named after someone you know.

2. Title Prompts

A good horror title doesn’t scream, it whispers. These prompts are designed to spark slow dream, suggestion, or a story you can feel before it even begins. Students can use them as direct inspiration, title-based challenges, or springboards into full narrative pieces.

1. The Room

2. Under the Floorboards

3. Thirteenth Bell

4. You Were Meant to Stay Asleep

5. Whispers from the Walls

6. The Rule

7. The Lights Went Out at Number 46

8. Three Days After the Funeral

9. Do Not Answer

10. The Copy in the Mirror

3. Opening Lines

A strong opening line in horror doesn’t just grab attention, it creates a sense of unease. These lines are designed to make students lean in, ask questions, and immediately feel that something is... off. Perfect for launching short stories, or timed narrative practice:

1. There was something breathing under the floorboards again/

2. We buried her on Sunday.

3. The first knock came at 2:08 a.m.

4. I knew something was wrong.

5. They told me not to open the envelope.

6. The photo changed overnight.

7. My shadow moved before I did.

8. We all agreed never to talk about what happened.

9. I heard my mum calling me from the kitchen.

10. I knew I was the only one that could see her.

4. Closing Lines

A horror story doesn’t need a neat ending, in fact, I think the best ones rarely do. These closing lines are designed to leave students (and readers) unsettled. Some offer silence. Some offer a final twist. All of them leave something behind:

1. I locked the door, but I could still hear breathing.

2. The room was finally silent, but I knew it wasn’t empty.

3. They all said it was just a story.

4. The light went out, but this time, it didn’t come back on.

5. I told the Police everything, every detail, except the part I still can’t explain.

6. He promised he wouldn’t follow me.

7. We closed the door, boarded the windows, and waited for morning.

8. I looked in the mirror and finally saw what everyone else had been seeing.

9. I think it’s stopped now.

10. I wasn’t scared, until I heard my voice coming from the other side.

5. Character Ideas

Good horror characters don’t have to be villains, sometimes they’re just people who looked away for a second too long. These prompts are built around fear, denial, guilt, or obsession. They’re perfect for exploring voice, perspective, and the moment everything changes:

1. The only only student who refuses to go near the old science classrooms, but won’t say why.

2. A child who draws people who haven’t died, but always do within days of the drawing.

3. A teenagers who sleepwalks, and always wakes up somewhere different and holding something new.

4. A teacher who keeps a list of names in their desk, but nobody knows why.

5. A twin who remembers a sibling, but no one else believes they existed.

6. A girl who talks to a her mirror, and it talks back.

7. A parent who insists their child came back “wrong” after a school trip.

8. A person who finds their own handwriting in a stranger’s notebook, on a page dated in the future.

9. A hiker who found something buried deep in the forest, and brought it home.

10. A stranger who shoes up in every family photo, going back decades.

6. Setting Ideas

The right setting in horror doesn’t just hold the story, it creates the fear. These settings are eerie without being overused, giving students the space to build slow dread, suspense, and sensory detail in unexpected ways:

1. An abandoned hospital wing that still smells like antiseptic and plays faint music through the speakers.

2. A forest clearing where no sound exists, not even birdsong.

3. A petrol station that only opens between midnight and 2 a.m., and the same car is always parked outside.

4. An old house that is completely empty, apart from a single ticking clock.

5. A train that is moving, but no stations ever appear.

6. A family home where every photo has one person scratched out, and no one will say who it is.

7. A theme park that never closes, but no staff are ever seen.

8. An abandoned and empty swimming pool, that still echoes with the sound of splashes.

9. The top floor of a high-rise apartment building, it’s been sealed off but nobody knows why.

10. A small town museum that hasn’t changed it exhibits in over 40 years, and still has a section marked “Coming Soon”.

7. Picture Prompts

I always think a single image can hold an entire story, or something trying to escape one. Horror picture prompts are some of the most powerful tools for classroom creativity. These eerie, atmospheric visuals create instant intrigue and tension, letting students explore fear, setting, and suspense in their own way. Use them for short stories, descriptive tasks, or as inspiration for a longer piece. No jump scares. Just quiet dread.

Final Thoughts

Horror is one of the most powerful genres for teen writers, not because it’s scary, but because it’s the one lots of them find most engaging. It demands atmosphere. It forces restraint. And it invites the kind of imaginative risks that lead to unforgettable writing.

You can also explore my Daily Writing Prompts, a subscription-based resource that gives you a brand-new prompt every single day (with the first month completely free).

Whatever you’re teaching, I hope these prompts give your students the same quiet chill that makes horror so unforgettable to write, and impossible to look away from.
