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.
Well, King's ability to create vivid and disturbing images also contributes to the scariness. In his novels, he describes grotesque scenes and terrifying creatures in great detail. For example, in 'It', the description of Pennywise the clown with its sharp teeth and menacing presence is enough to send shivers down your spine. His characters are often complex and flawed, which makes them more relatable, and thus, when they are in terrifying situations, it becomes even scarier for the readers.
For novels like 'Salem's Lot', it's the transformation of a normal town into a place full of vampires. The slow takeover, the people you know turning into blood - sucking creatures, and the feeling of being trapped in a place where evil is spreading. Also, King's vivid descriptions make it seem so real, as if it could be your own town that gets infected.
For his scariest novels like 'It', the ability to tap into universal fears is key. Fear of the unknown, fear of something lurking in the shadows. Pennywise represents that unknowable evil that can be anywhere. Also, the detailed descriptions of the town and the sewers where It hides make it seem more real and thus scarier.
For his scariest novels like 'It', the fear of the unknown is a big factor. We don't fully understand the true nature of It. Also, the vulnerability of the children characters makes it scarier as we naturally want to protect the young. And the fact that It can be anywhere, hidden in the sewers or disguised as something friendly, is truly terrifying.
In 'The Shining', the setting plays a huge role. The large, empty, and haunted hotel. The long corridors and the feeling that something is always watching. Also, Jack's transformation from a normal father and husband to a crazed killer adds to the horror. It shows how isolation and the power of the hotel's evil can break a person.
For many of his scariest stories, it's the way he taps into our deepest fears. Like in 'It', the fear of the unknown and of things that go bump in the night. He also creates really vivid and disturbing characters. In 'The Shining', Jack Torrance's transformation is both believable and horrifying.
In 'The Exorcist', the realistic portrayal of demonic possession makes it so terrifying. The struggle between good and evil within a young girl's body is really disturbing. In 'Pet Sematary', the violation of the natural order of life and death is what makes it scary. And in 'It', the idea of an evil entity that can take different forms and prey on children is truly nightmarish.
For '1984', it's the total lack of privacy. Big Brother is always watching, and the Thought Police can arrest you for your thoughts. In 'The Handmaid's Tale', it's the subjugation of women. They are stripped of their rights and used as vessels for reproduction. In 'Brave New World', it's the loss of true human nature as people are engineered and conditioned from birth.
What makes a scariest story terrifying is often the sense of the unknown. When there are elements in a story that we can't explain, like a strange noise in a haunted house with no obvious source, it sends shivers down our spines. It plays on our fears of the dark and the unseen.
The way he creates a sense of unease. His vivid descriptions of ordinary places turning into something menacing. For example, in some stories, a simple small town becomes a place full of hidden horrors.
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.
