Have you ever heard of any plane horror stories?

Yes. There was a story about a person who accidentally dropped their phone into the toilet while pooping. They had to quickly fish it out, and it was all wet and disgusting. And they didn't know if it would still work.

Yes, I've heard of a story where a woman was followed onto the subway by a stalker. She noticed him on the platform and thought nothing of it at first, but then he got into the same car as her. He sat close and stared at her the whole time, making her extremely uncomfortable.

Yes, I've heard of the story where a flight attendant saw a ghostly figure in the cockpit during a night flight. She said it was a transparent man who seemed to be looking at the controls as if he was still flying the plane.

I haven't had the chance to hear about a 'dulcimer horror story'. However, if such a story exists, it might play on the idea of the dulcimer as an object that has been forgotten or lost in time. The horror could stem from the discovery of the dulcimer and the secrets it holds. For instance, it could be that the dulcimer was used to communicate with the dead in the past, and when it's found again, it starts to draw in the spirits of the netherworld, causing chaos and fear for those around it.

No, I haven't heard of it specifically. It could be a very niche or newly created concept.

Yes, I've heard one. There was a story about an old abandoned house. People said that at night, strange noises could be heard from it, like someone was dragging heavy chains. And there were faint white figures seen in the windows.

I've heard a true ghost story from my friend. There was this abandoned hospital where strange noises were always reported. One night, a security guard saw a shadowy figure in the corridor. He was so scared that he quit his job the next day. It might be the ghosts of patients who passed away there.

I've heard a story where a group of divers went to explore a newly discovered reef. While they were there, one of them saw a figure that looked like a drowned sailor floating above the reef. The figure seemed to be beckoning them. The other divers didn't see it at first, but when they turned around, they saw a strange mist. They quickly ascended, and since then, they've been reluctant to go back to that reef. It could be that their minds were playing tricks on them due to the unfamiliar and somewhat alien environment underwater.

Well, I know a story where a boy was so nervous for a big test that he vomited right in the exam room. It disrupted the test for a while as the teachers had to take care of him first. This shows that excessive stress can have physical effects on students.

Sure. There's a mountaineering ghost story where a group of climbers found an abandoned tent on the mountainside. Inside the tent, there were signs of a hasty departure. That night, they heard eerie howls. They thought it was a wild animal at first, but then they saw a shadowy form passing by their campsite. They never found out what it really was.
