Words like 'throbbing', 'pulsing', and 'whispering' can build tension. 'Throbbing' might be used to describe an evil presence that seems to have a life of its own. 'Pulsing' gives a sense of something building up. 'Whispering' makes the reader feel like there are secrets or threats being shared quietly, adding to the unease.
Use words like 'creeping', 'looming', and 'hovering'. 'Creeping' gives the sense of something slowly approaching in a menacing way. 'Looming' makes it seem like a threat is about to descend. 'Hovering' creates an uneasy feeling of something being there but not fully showing itself.
Use words like 'ominous' and 'threatening'. For example, 'An ominous cloud hung over the old mansion.' The word 'ominous' immediately makes the reader feel that something bad is going to happen in that mansion. Also, 'threatening' can be used to describe a character or a situation, like 'The threatening figure emerged from the fog.'
Tension can be built by introducing unexpected twists and turns. Maybe a trusted ally betrays the protagonist or a seemingly easy solution turns out to be a trap. Additionally, ratcheting up the stakes for the characters makes the story more tense.
You can start by creating a sense of uncertainty. Make readers wonder what's going to happen next. Also, build up to important events slowly to increase anticipation.
One way is to use slow pacing and build up suspense gradually. Let the reader or viewer wonder what's coming next.
You could start with a character who has a dark past that they are trying to hide. For example, they might have committed a crime long ago. Then, slowly introduce elements that make them suspect that someone is onto them. This creates suspense as the reader wonders if they will be caught.
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.
One way is to introduce time pressure or deadlines for the characters. When they have to act quickly, it naturally creates tension.
One way is to create a sense of time pressure. Make the characters have a limited amount of time to achieve their goal.
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.
Build tension through setting. A dark, spooky forest or an abandoned, dilapidated house can create an atmosphere of unease. If your characters are in such a setting, the tension will be palpable. You can also use pacing. Slow down the narrative when something crucial is about to happen, like a character making a life - changing decision. This draws out the moment and increases the tension.
