The unexpected and abnormal behavior is really scary. Like when they start acting in ways that are not part of their normal programming.
The idea that they could be 'possessed' or malfunction in a way that makes them seem evil. In some stories, they seem to target specific people, like staring at one person in the room constantly. It creates an atmosphere of unease and makes people wonder if there is something more to these toys than meets the eye. Furbies are supposed to be cute and friendly, but when they deviate from that, it's very frightening.
The noises they make can be quite terrifying. For example, if they start making deep, guttural sounds instead of their usual high - pitched voices. It gives the impression that there is something malevolent inside them. Also, the fact that they seem to have a 'life' of their own, like moving around or changing positions without any obvious cause, is really spooky.
In one story, a Furby started whispering things that sounded like gibberish at first. But when the owner played it back and slowed it down, it seemed to be saying some really disturbing words. This made the owner feel very uneasy and they ended up getting rid of the Furby.
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.

The sudden movement of the LPS toys when they're not supposed to be able to move is really scary. It goes against what we know about them as inanimate objects.
The unknown and the supernatural. Take the Black Shuck for instance. A huge, black spectral dog just appearing out of nowhere is terrifying. There's no rational explanation for such a thing, and that's what makes it so spooky in UK horror stories.
The loss of control. When someone is hypnotized, they are in a vulnerable state. In horror stories, this often means they can be made to do things against their will, like harming themselves or others, which is really scary.
In Tamil horror stories, the unknown and the unexpected are really scary. There could be a strange noise in an empty room, or a shadow that moves on its own. Take a story where a family moves into a new house. At night, they hear scratching sounds from the attic, but when they check, there's nothing there. It builds up the fear as you don't know what's causing it. Another scary aspect is the use of local superstitions. For instance, if a black cat crosses your path in a Tamil horror story, it's often a sign of impending doom.
