When a king is associated with the macabre and the supernatural, it can be really scary. Like King Vlad III and his connection to the Dracula legend. The idea of a king being so cruel that he becomes a symbol of horror in folklore, with stories of impaled bodies and a blood - thirsty reputation, makes for a truly terrifying king story.
The settings are important too. For example, in 'The Shining', the haunted Overlook Hotel is a place full of mystery and danger. Isolated and with a dark history, it sets the perfect backdrop for a scary story. The sense of being trapped in such a place adds to the horror.
One of his scariest stories could be 'It'. The idea of a shape - shifting, child - killing entity that can take the form of your worst fears is truly terrifying. Pennywise the Dancing Clown is an iconic and frightening villain.
I think 'Survivor Type' is extremely scary. It's about a man stranded on an island and the lengths he goes to in order to survive, including some truly gruesome acts. It makes you question how far a person can go when pushed to the brink, and the vivid descriptions add to the horror.
I'd say 'The Shining' is up there. The isolated hotel, the descent into madness - it's a terrifying ride. The way King builds up the tension and horror is masterful.
In 'Pet Sematary', it's the distortion of something as natural as death and the afterlife. We expect death to be final, but when that's subverted and the dead return in a wrong way, it messes with our fundamental beliefs. King is a master at taking normal things and making them into sources of horror. He also has a great way of creating a sense of unease and building suspense throughout the story. For instance, in 'The Shining', the slow descent of the father into madness as they are isolated in the hotel is a gradual build - up of horror that keeps the readers on the edge of their seats.
The size of the ant king can be really scary. Just imagining a huge ant-like creature is quite terrifying.
One of his scariest short stories could be 'The Mist'. The sense of isolation and the unknown horrors lurking in the mist create a terrifying atmosphere. The characters are trapped in a supermarket, surrounded by the mist that holds all kinds of deadly creatures. The psychological tension as they try to figure out what to do and face their possible doom is truly spine - chilling.
The psychological depth. Stephen King has a knack for getting into the minds of his characters. In his scariest short stories, he often explores the darkest corners of the human psyche. For example, in 'The Mist', the fear of the unknown and the breakdown of society under extreme circumstances play on our deepest insecurities.
Well, 'The Stand' has its share of scary elements. The apocalyptic scenario and the battle between good and evil are really intense. However, if we talk about pure horror, 'Cujo' is up there. A rabid dog trapped with a mother and son in a car is a simple yet extremely terrifying concept. Also, 'The Dark Half' with its doppelganger theme, where the main character has to face his dark, murderous other self, is quite spooky.
I think 'Pet Sematary' is also very scary. The idea of a burial ground that brings things back to life, but not in a normal way. The resurrected beings are often corrupted and bring a sense of unease and horror. It plays on our fears of death and the unknown.
