A short scary story works when it has a sudden twist or unexpected ending. It should build tension quickly and leave you with a chill.
A short scary story is effective when it can shock or surprise you in a short amount of time. Maybe it has a simple but terrifying concept, or it plays on common fears in a unique way.
Character development can contribute to the effectiveness of a scary short story as well. If the reader can empathize with the characters, their fear and panic become more palpable. For example, if a character is a loving mother trying to protect her children from an unknown evil in a story, the reader will be more invested in her struggle and feel the horror more acutely.
One key factor is the element of surprise. For example, in a story where a character seems safe, and then suddenly something terrifying jumps out. It catches the reader off - guard.
A short scary story is effective when it has an element of the unknown. For example, if you don't clearly show what the monster or the danger is, it leaves the reader's imagination to fill in the gaps, which can be really terrifying. Like in a story where you just hear strange noises in a dark room but don't know what's making them.
Characterization can make a scary short story effective. If you can empathize with the character's fear, it makes the story more impactful. In 'The Open Window', the main character's confusion and growing unease as the girl tells her strange story draws you in. Also, a sense of dread that builds throughout the story, like in 'The Red Room' where the narrator gradually realizes there is something truly menacing in the red room, is very important.
One factor is the atmosphere. A dark, gloomy and tense atmosphere can immediately put the reader on edge. For example, in 'The Tell - Tale Heart', Poe uses descriptions of the old man's room at night and the slow, stealthy movements of the narrator to create a sense of dread. Another is the element of the unknown. When the reader doesn't know what's going to happen next or what the true nature of the horror is, it's much scarier. Like in 'The Call of Cthulhu', the vast and incomprehensible nature of the cosmic horror is what makes it so effective.
Good use of atmosphere. If a story is set in a dark, abandoned place like an old asylum. The description of the damp walls, broken windows, and cold air adds to the creepiness. Also, the characters' vulnerability, like a lone traveler in a spooky forest, makes the danger seem more real and the story scarier.
Effective short scary ghost stories often have relatable characters. When the reader can put themselves in the character's shoes, it becomes scarier. Imagine a story about a person staying alone in a hotel room, which is a common experience for many. Then, if a ghost starts to haunt that room, the reader can better feel the fear. Additionally, using simple yet vivid language to describe the ghost, like 'a figure with a tattered white gown and hollow eyes' can quickly create a scary image in the reader's mind.
One key factor is the setting. A spooky, isolated place like an abandoned asylum or a dark forest immediately sets a scary mood. For example, in 'The Haunting of Hill House', the old, decrepit mansion is as much a character as the people in the story. Another important element is the use of suspense. Keep the reader guessing what will happen next, like when a character hears a strange noise but doesn't know what it is yet. Also, vivid descriptions of the terrifying elements, such as a grotesque monster with dripping fangs, can really make a scary story effective.
The element of the unknown is also crucial. A short scary ghost story doesn't have to show the ghost clearly all the time. For instance, if you just hear strange noises, see a fleeting shadow, or feel a cold presence without really knowing what it is, it creates more fear. In a story where the main character just hears scratching noises under their bed but never sees what's causing it, it's scarier than if they saw a full - on ghost immediately.
Suspense is key. For example, in a short story, if you start with a character alone in a spooky place like an old cemetery at night, and you build up the tension by having them hear strange noises but not see anything right away. It makes the reader keep reading to find out what's going to happen.
