However, in many such stories, there is often a protagonist who is curious and determined to figure out what's going on with the ghosts. There might also be a sidekick or a love interest for this main character. Additionally, there could be an antagonist, perhaps someone who is causing the ghosts to be more menacing or is using the ghostly situation for their own malicious purposes, like a greedy developer who wants to build on the haunted land and disturbs the spirits, and then tries to cover it up by making the others seem crazy when they start seeing ghosts.
There could be a local on the fantasy island who has always sensed something strange but never fully understood it until the events of the ghost story unfold.
