Stephen King often plants little hints and foreshadowing throughout the story. These small clues make the reader aware that something bad is coming, but not exactly what it is. And he also plays with the readers' emotions. He might make us feel sympathy for a character and then put that character in a terrifying situation, which heightens the tension.
In his short stories, King creates complex and relatable characters. We become invested in their fates. As the danger approaches them, we feel the tension rising. He also uses elements of the supernatural in a very subtle way at first. It starts as something that could be explained away, but then it gradually becomes more and more menacing, building a great deal of tension as it goes.
He uses foreshadowing. King drops little hints early in the story about what might come later. This makes the reader anticipate and be on guard for something bad or strange to happen.
He uses vivid descriptions. For example, in 'The Boogeyman', he describes the dark corners and the unknown lurking there. This makes readers feel the unease.
The story could build tension by creating a sense of helplessness. In the diary, if the girl is in a situation where she has no control, like being trapped in a haunted place. Also, the pacing matters. If it slowly unfolds events, like she starts to notice a strange smell in the house one day, and then over the next few days, other strange things occur, it builds tension. And the use of foreshadowing, like she mentions a strange dream before the real horror starts, can also build tension.
They build tension by being unexpected. When you least expect it, you hear those footsteps, and it immediately grabs your attention and makes you feel on edge.
He uses details. Every creak of the floorboards in the room, every shadow in the corner can be a source of suspense. By describing these small things in a vivid way, he makes the reader feel as if they are in the room too and are on edge.
He uses the unknown. The mist itself is a big mystery. We don't know what's in it at first, which creates immediate suspense. Also, the slow revelation of the creatures. He doesn't show all the terrifying things right away. Instead, he gives little hints and glimpses, like the tentacles at the beginning. This keeps the reader on edge, wondering what else is lurking.
You can also use the power of the unknown. Don't reveal too much too soon. Just give hints about what might be out there. For instance, the character hears a growl, but they don't know what kind of creature it could be. Is it a wild animal? Or something more sinister? Also, create a sense of isolation for the character. If they're alone in a big, empty place, it adds to their vulnerability and the tension of the situation. And don't forget to use short, choppy sentences when the action starts to pick up to increase the sense of urgency.
Stephen King builds suspense by creating complex characters. The shooter isn't just a one - dimensional villain. He might give the shooter some relatable qualities or a backstory that makes the reader feel a sense of unease. We start to wonder how someone who could have some good in them could do such a terrible thing. Also, he may use the setting of the school. The familiar and usually safe environment of a school turned into a place of danger creates a lot of suspense.
The character of 'It' itself is a great suspense - builder. Since 'It' can take different forms, the readers are always on edge, not knowing what form 'It' will take next. Also, the pacing of the story helps. There are slow, tense moments where the characters are just waiting for something to happen, and then sudden, terrifying events.
Using the element of time can be very effective. If you set a deadline or a ticking clock situation, like the protagonist has to get out of a haunted place before sunrise, it creates a lot of tension. Every second that passes makes the situation seem more and more dire, and the reader feels the pressure along with the character in the story.
