Well, if a potato tells a ghost story, it might not be very effective at first. After all, who would expect a potato to be a storyteller? But as the story unfolds, perhaps it could create a really eerie atmosphere. Imagine the potato talking in a low, hushed voice about a ghost that haunts the cellar where it used to be stored. It could make the other things in the cellar, like the old barrels and sacks, seem a bit more spooky.
Of course, the ghost itself is a character. It could be a former inhabitant of the place, like a long - dead nobleman or a servant who met a tragic end. And there could be other secondary characters like the protagonist's friends who either believe or don't believe in the existence of the ghost and their reactions add to the story's drama.
I'm not entirely sure which specific ghost story Chie tells in that instance. There are so many interesting stories in Persona 4 Golden that it's hard to recall this one off the top of my head.
Maybe it's the sudden appearance of the ghost in the story. Just imagine, in the dark night, a shadowy figure suddenly emerges from nowhere, that would be really terrifying.
Well, often there could be a spooky old house. Maybe a strange noise that comes at midnight, like creaking floors. And there might be a shadowy figure that lurks in the dark corners.
