To write an essay on a ghost story, you need to do research if it's based on a real - life legend or a particular cultural ghost story. Decide on the theme, such as revenge or lost love. Use vivid language to describe the supernatural elements. For instance, instead of just saying 'the ghost was scary', say 'the ghost's eyes glowed with an otherworldly light, sending shivers down the spines of those who beheld it'. Also, analyze the significance of the ghost story in terms of its cultural or psychological impact on the audience.
Begin by choosing a type of ghost story. It could be a traditional gothic ghost story with dark castles and tortured spirits, or a modern - day ghost story set in an ordinary place like an apartment building. Next, develop your characters. They should be believable so that when they experience the supernatural, the reader can empathize. When writing the essay, structure it in paragraphs. Each paragraph should contribute to the overall narrative of the ghost story. You can also compare and contrast different ghost stories to add depth to your essay.
