One of the scariest parts is when their actions seem to have no logical explanation. Maybe they lock themselves in the bathroom for hours making strange noises, and when they come out, they act as if nothing happened. And if they have a violent streak, like randomly breaking things or threatening you, that's extremely terrifying. It makes you constantly on edge, not knowing if you'll be the next target of their outburst.
For me, it's when they invade your personal space in a really creepy way. Like going through your stuff without permission or standing too close to you all the time. It makes you feel violated and unsafe. In a horror story, this could be intensified when they start leaving strange objects in your personal area. Also, their abnormal behavior like talking to unseen entities can be really frightening as it gives an air of the supernatural.
The sudden and unexplained changes in behavior are really scary. For example, if a roommate who is usually friendly suddenly becomes cold and distant, and starts doing strange things like talking to themselves or staring blankly. It gives a feeling that something is seriously wrong.
My psycho roommate used to collect dead insects. He would put them in little boxes all over our shared room. The smell was awful. And he had this habit of coming into my space when I was out and moving my things around. One day, I found a dead mouse in my drawer. I'm sure it was his doing. I immediately found a new place to live.
Well, the scariest parts are when the horror seeps into the most innocent parts of Christmas. Like when the presents start to have some sort of dark magic or when the Christmas carols are distorted into something eerie. It's like taking all the warm and fuzzy feelings we associate with Christmas and turning them into sources of fear. And when there are jump scares in the middle of a supposed - to - be - happy Christmas scene, that really gets the heart racing.
The sudden and unexplained noises are really scary. For example, in many stories, there are strange creaking sounds or thuds that make the babysitter jump. It creates a sense of unease right away.
The loss of control. When people are on PCP, they often do things they would never do sober, like attacking others or harming themselves.
In an Emily horror story, the moment when Emily realizes she's completely alone and there's no one to help her can be really terrifying. Like when she was in the forest camping and all she had was her tent against whatever was out there with the glowing eyes. She knew she couldn't just run to safety easily.
As I'm not aware of the 'daenys horror story', it's hard to say. But in horror, often the unknown and the unexpected are the scariest elements. For example, a character being alone in a strange place and having a feeling that something is very wrong but not knowing what it is. Also, the loss of control and the threat to one's safety can be terrifying aspects in a horror story.
The scariest part could be the financial loss. When you invest a lot of money in decoration and it all goes wrong, like in the case where you pay for high - quality materials but end up with cheap and shoddy ones. It's a big blow to your wallet.
The scariest part is often the loss of control. When under the influence of salvia, people can't direct their thoughts or actions. So in a horror story, this could mean being at the mercy of the terrifying hallucinations.
As I don't know the story, I can't say for sure. But in horror stories, sudden and unexpected events are often the scariest. Maybe in 'the call horror story', it's a really creepy voice on the call that suddenly says something terrifying.
