Well, one common theme is the unknown. These scary stories by J daughter might often play on the fear of not knowing what's out there in the dark. Another theme could be monsters. It could be a werewolf or some strange creature from the deep forest. And death is also a possible theme, with stories revolving around curses that bring about death.
Use vivid descriptions. For example, describe the monster in great detail, its appearance, how it moves. Also, build suspense. Don't reveal the scary part all at once.
There might be a story where the J Daughter encounters a strange figure in the forest. It was a dark and foggy night, and this figure seemed to be following her. As she ran, she could hear its heavy breathing getting closer. It turned out to be a lost soul, forever wandering in the forest.
The masked ghost lady could be a local storyteller known for her spooky tales. She might have a mysterious past herself that adds to the allure of the stories she tells.
Jackal. Jackals are often associated with death and the afterlife in some cultures. In a scary story, a pack of jackals could be seen as harbingers of doom. They could lurk around an old cemetery, howling at night, and their eyes glowing in the dark, creating a spooky atmosphere.
Jinx. It can be used in a scary story as a kind of curse or omen. For example, a character might be jinxed by an evil witch, and from then on, all kinds of bad things start to happen to them, like strange noises following them everywhere, and objects in their house moving on their own.
You could also consider a horror - themed movie collection on DVD. Movies like 'The Sixth Sense' or 'Psycho' are well - known and might be something your mom would enjoy, especially if she likes a bit of a scare while watching a story unfold.
