Uncertainty plays a big role too. In military operations, soldiers often don't know what the enemy is planning. They might be walking into a trap or facing a new type of weapon they've never seen before. This lack of knowledge about what's coming next adds to the scariness.
Isolation can also make military stories scary. Imagine a small unit cut off from the main force, deep in enemy territory. They have no backup, limited resources, and are surrounded by the enemy. They must rely solely on themselves to survive, which is a very frightening situation.
The threat of death is a major element. When soldiers are in combat, they are constantly at risk of being killed or seriously injured. For example, in a firefight, bullets are flying everywhere, and one wrong move can be fatal.
The atmosphere is crucial. Dark, desolate settings like old mansions or abandoned asylums create a sense of dread. Another element is the element of the unknown. If a character in a story hears strange noises but can't figure out where they are coming from, it builds suspense. For instance, in the haunted house story, the couple heard whispers but couldn't tell who or what was making them.
One element is the power of nature. Thunderstorms can be so violent that they make you feel small and helpless. High winds that howl like angry beasts, rain that comes down in sheets so thick you can't see far, and hail that pounds on roofs and windows. Also, the unknown. If there are strange noises during a thunderstorm, like creaking in an old attic or something scratching at the window, it's easy to let your imagination run wild and think of all kinds of spooky things.
Sacrifice is a big element. In military love stories, often one or both partners have to sacrifice time together due to deployments or training. For example, a soldier may miss important family events like birthdays or anniversaries. This sacrifice for the greater good adds depth to their love.
The unknown nature of bigfoot makes the stories scary. We don't really know what it is, if it's real or not. Just the idea that there could be a large, ape - like creature out there in the woods that we don't understand is spooky.
Surprise is a big element. For example, when you think a character is safe and then suddenly something jumps out at them. It catches the reader or listener off - guard.
The contrast between cute and scary. For example, a small, innocent - looking creature like a bunny in a spooky setting. The bunny's cuteness makes the scary elements around it, like a haunted forest it might be in, more interesting.
Their behavior can be a big factor. If they act unpredictably, like suddenly disappearing and then reappearing in a strange place. Also, if they are overly strict or seem to be hiding something. I heard of a security guard who wouldn't let anyone near a certain area but never gave a good reason.
Isolation also plays a role. When you're alone, like when I was camping and saw those glowing eyes, you feel more vulnerable. There's no one around to help you, and your mind starts to play tricks on you. You imagine all sorts of horrible things that could happen. Another element is the setting. An old, abandoned place like the house I went into as a kid has an eerie atmosphere that adds to the scariness. It's full of mystery and decay, and it just gives off a feeling that something bad is going to happen.
The depth of water wells can be very scary. It gives a sense of the unknown and the feeling that once you fall in, there's no easy way out. For example, in many stories, people who fall into wells are doomed because the depth makes rescue almost impossible.
The element of the unknown. In a short 2 - minute story, not having all the answers makes it scarier. For example, in a story about a strange noise in the basement, not knowing what's making the noise creates fear. Also, sudden and unexpected events like a door slamming shut on its own can startle the listener.
