Weird fiction is a subgenre of speculative fiction that blends elements of horror, fantasy, and science fiction. It often features bizarre, surreal, or supernatural themes that challenge conventional storytelling. Authors like H.P. Lovecraft and Algernon Blackwood are known for their contributions to this genre, creating unsettling atmospheres and exploring the unknown. This genre frequently includes strange creatures, alternate realities, and existential questions, pushing the boundaries of reality. Unlike traditional horror, weird fiction often leaves readers with a sense of ambiguity, inviting them to ponder the mysteries of existence and the limits of human understanding.
