In 'The Ring', the cursed videotape is really frightening. Once you watch it, you are doomed to die in a horrible way. In 'A Nightmare on Elm Street', Freddy Krueger, who can invade people's dreams and kill them, is the scariest part. His burned face and the way he toys with his victims in their dreams are bone - chilling.
For 'The Amityville Horror', the idea of a haunted house that has a dark past and causes all kinds of strange and malevolent happenings to the new family is quite scary. And in 'Rosemary's Baby', the slow realization by Rosemary that she is carrying the devil's child is a very disturbing and scary element.
In two - story horror stories, the use of stairs can be a very frightening element. Stairs are often narrow and can be a bottleneck. If something is chasing you, the stairs can slow you down. Also, the upper or lower levels can have different atmospheres. The first floor might seem normal, but as you go up to the second floor, there could be a completely different and more menacing environment. Dark corners and hidden rooms on either floor add to the scariness as well. For instance, a hidden room on the second floor where strange noises come from can be terrifying.
The scariest elements often include the unknown. For example, in stories where there is something sensed but not seen clearly. Like 'I felt a presence in the dark corner. When I turned on the light, the presence was gone but a cold draft remained.' Here, the unknown presence is very frightening.
Another really scary one could be 'My phone rang at 3 am. The caller ID said it was me.' It plays on the idea of the self being something other or unknown, and calls at that time are always spooky.
The unknown is the scariest. In 'as is horror stories', things are often left in their natural state, so you don't really know what's lurking in the shadows or what's causing those strange noises. It's that sense of not having all the answers that makes it terrifying.
Isolation is also a key element. When characters are alone in a spooky place, like an abandoned asylum in one of the stories. They have no one to turn to, and that makes the situation even more terrifying as the horror unfolds around them.
The unknown is one of the scariest elements. When things are not clearly defined, like a strange figure in the fog in some stories from '1001 horror stories', it makes our imagination run wild. We start to create the most terrifying scenarios in our minds.
The scariest element could be the sense of the unknown. For example, in many stories, there are strange noises or happenings that the characters can't explain. It's that not - knowing what is causing the fear that really gets to you.
The isolation in many of the stories is really scary. Like when a character is alone in an old, abandoned building, cut off from the outside world, and they start to feel like they're being watched by something malevolent. There's also the fear of the supernatural, such as ghosts or demons that defy the laws of nature. This makes the characters, and the readers, feel powerless against them.
The sense of helplessness is a major scary element. Like when a character realizes that there's no way to escape from El Coco once it has arrived. It gives a feeling of doom and despair. For instance, in a story where a person is trapped in a small space and El Coco is approaching, they know they can't get away. This powerlessness is what makes these stories truly frightening.
I think 'I heard a child crying in the basement. But I live alone.' is quite terrifying. The idea of a crying child in a place where no child should be, especially when you live alone, plays on our fears of the unknown and the supernatural. It makes you wonder what could be down there, and the thought that it's not a normal, explainable situation is very frightening.
