A Boggart is a creature from English folklore, often described as a mischievous spirit or goblin. Traditionally, Boggarts are known for causing trouble in homes, such as hiding objects or creating disturbances. They are often associated with specific locations, like marshes or old houses, and can take on various forms, including that of a cat or dog. In literature, Boggarts have been popularized by works like the Harry Potter series, where they are depicted as shape-shifting creatures that reflect a person's fears. In this context, they serve as a metaphor for confronting one's anxieties and challenges.
