Why was the ghost angry with the ouija board fanatics from the chapter a shaduy plot?

In "A Shady Plot" by Elsie Brown, the ghost is angry with the Ouija board enthusiasts because they disrupt its peace by attempting to communicate with it without understanding the consequences. The ghost feels disrespected by their frivolous approach to the supernatural, as they treat serious matters lightly. This lack of reverence for the spirit world ultimately provokes the ghost's ire, leading to chaotic and comedic situations throughout the story.
