The scariest thing could be finding out that the person you're with has a dark secret. For example, they might be a serial killer who has lured you to the isolated romantic cabin to harm you. Another scary thing could be the presence of ghosts. Maybe the cabin was built on an ancient burial ground, and the spirits are angry that you're there. Also, getting trapped in the cabin during a blizzard or a flood while something strange is going on inside would be terrifying.
Perhaps the scariest thing would be if the cabin seemed to come alive. The walls might start to close in on you, the floorboards creaking as if they were trying to trip you up. Or there could be a hidden room in the cabin that reveals a horrible past. Maybe it was used for torture or some other evil deeds, and the energy of that past still lingers. And if all communication with the outside world is cut off suddenly, like your phone stops working and the roads are blocked, and then the strange things start to happen, that would be really frightening.
The scariest thing could be seeing a ghostly apparition. Imagine lying in bed and suddenly seeing a transparent figure floating above you.
The exhibits coming to life all at once. Imagine all the statues, the mummies, the prehistoric creatures suddenly being animated and surrounding you. There would be no way to escape as they closed in, each with their own strange and menacing presence.
The scariest thing could be getting trapped inside with some kind of malevolent spirit. For example, the doors could close on their own and no matter how hard you try to open them, they won't budge. And then you start seeing apparitions floating around the aisles, reaching out to you with their cold, ghostly hands.
The scariest thing could be seeing a ghostly apparition. For example, a figure that looks like it's from another era, all pale and transparent, just floating around the tombstones. It gives the impression of being lost in time and yet somehow very menacing.
The scariest thing could be getting lost in a maze - like abandoned part of the station. You know, like there are these old tunnels and corridors that no one uses anymore. And you end up there all alone, with only the sound of dripping water and your own echoing footsteps. And then you start seeing strange markings on the walls, as if something was trying to communicate or warn you.
The scariest thing could be seeing a ghostly apparition. Like a figure that appears and disappears, leaving you with a feeling of dread. It would be terrifying if it just stared at you without saying a word.
Well, getting locked inside the supermarket overnight could be terrifying. All the lights go out, and you're surrounded by rows and rows of silent shelves. You might start hearing strange noises from the freezers or the storage rooms, not knowing what could be making those sounds. And with no one to help you, it would be a truly scary situation. There could also be some strange, unexplained events like products flying off the shelves or the cash registers starting to ring on their own. It would make you feel like you're in a horror movie.
A wife in a cabin in the woods could have a very relaxing time. She could spend her evenings stargazing. During the day, she might explore the woods and find an old tree with a hollow big enough for her to sit in. She could use the resources around her to make handicrafts, like weaving baskets from twigs she finds on the forest floor. This would be a great way for her to unwind and connect with nature on a deeper level.
For me, the scariest part of the 1999 story was the Columbine shooting. It was so unexpected and the violence was extreme. Innocent students and teachers were just going about their normal day and then suddenly faced this horror.

They might debate whether to involve the higher - ups or keep it to themselves for a while.
