Well, in many horror mirror stories, there is a history attached to the mirror. It could be that the mirror has been part of some dark ritual in the past or has witnessed a great tragedy. This history then seeps into the present and affects those who come in contact with the mirror. Also, a change in the environment around the mirror is common. For example, the room might get colder or there could be a strange smell when the mirror starts to act up. And of course, the people who interact with the mirror usually start experiencing strange and terrifying events in their real lives that seem to be related to what they saw in the mirror. This creates a sense of dread and paranoia.
The most common element is the element of the unknown. We don't really know what's on the other side of the mirror, and that scares us. In horror mirror stories, the mirror often becomes a gateway for the supernatural. It might show things that haven't happened yet, like premonitions of death. Another element is the isolation of the person with the mirror. Usually, the person is alone when they start to notice the strange things about the mirror. This isolation heightens the fear because there's no one immediately there to help or confirm that what they're seeing is real. And often, there's a sense of being trapped. Once the horror starts with the mirror, it's hard for the characters to escape from it, whether it's because they can't stop looking at it or because the mirror's influence spreads beyond just the visual and affects their entire surroundings.
One common element is the distortion of the reflection. For example, the face in the mirror might change into something grotesque, like a monster or a ghost. Another element is that the mirror often seems to have a life of its own. It might emit strange noises or a strange glow. Also, the mirror can act as a portal to another world or time, showing things that are not supposed to be there, like a past tragedy or a spooky alternate dimension.
The distortion of one's own reflection can be really scary. For example, seeing your face change in the mirror without any logical reason.

Also, often there's a connection to a past event or a previous owner in the place where the mirror is located. Maybe someone died there and their spirit is trapped in the mirror.

The appearance of the ghost itself is a common element. Usually, it has a pale complexion, hollow eyes, or some other eerie feature. It might also be associated with a tragic backstory, like a person who died unfairly in the house where the mirror is. This gives the ghost a reason for haunting and makes the story more engaging. For instance, a woman who was killed by her lover might haunt the mirror, seeking revenge or just trying to tell her story.

Horror stories often feature a protagonist who is in over their head. They might start out as an ordinary person, like in 'Rosemary's Baby' where Rosemary is just a normal woman, but then they are thrust into a terrifying situation. Settings also play a big role. Abandoned asylums, cemeteries, and old mansions are common settings in horror stories as they have an air of mystery and danger already associated with them.
Fear of death is a big element in horror stories. The threat of death, whether it's from a serial killer or a supernatural force, is always present. Also, there's often a sense of helplessness. The characters find themselves in situations where they seem to have little control over what's happening to them. For instance, in 'The Blair Witch Project', the characters are lost in the woods and being hunted by an unknown entity. There's also the use of suspense. Writers build up the tension by delaying the reveal of the horror, making the readers or viewers more and more anxious as the story progresses.
