One common element is the sense of mystery. The darkness of the cavern hides many things that are unknown. Another is the feeling of isolation. When you're in a cavern, you're cut off from the outside world. Danger is also a common element, like the possibility of getting lost or encountering unstable rocks.
Yes, it can be very dangerous. Collapsing a cavern without proper knowledge and planning can lead to cave - ins, which might harm people nearby. And the fact that there's a ghost story associated with it doesn't change the physical risks.
A 'dark cavern story' might involve a hermit who lived in a dark cavern for years. People thought the cavern was haunted, but the hermit knew it was just a place full of natural mysteries. He would often see bats flying around at night and the dripping water creating an otherworldly sound. He felt a strange connection to the cavern, as if it was protecting him from the outside world.

One common element is the feeling of isolation. When you're in a boat in a dark cavern, you're cut off from the outside world. Another is the use of limited light sources, like a lantern on the boat. This creates a contrast between the small pool of light and the vast darkness around. Strange geological formations in the cavern, such as narrow passages or large open chambers, are also common. And often there's a goal or purpose for the boat ride, like finding an exit or looking for something that was lost in the cavern long ago.
The plot could involve a group of adventurers taking a boat ride in a dark cavern. They might encounter strange creatures like glowing fish or bats. There could be hidden passages and they may be in search of a lost treasure.
There was a story about a solo explorer in a dark cavern. He got lost but managed to find his way by following a small underground stream. Along the way, he saw some unique cave-dwelling creatures that he had never seen before. It was a thrilling yet terrifying experience for him.
I'm not sure if it's a good idea to collapse a cavern just because of a ghost story. However, if there are safety concerns, proper engineering surveys and procedures need to be carried out. Maybe consult with geologists and mining engineers first.
Sure. In a mobile phone service, if a customer churns to another provider. The original provider can offer special deals later, like more data at a lower price. If the customer is attracted back, it shows churn wasn't the end.
