Although "weird fiction" is chiefly a historical description for works through the 1930s, the term has also been used since the 1980s, sometimes to describe slipstream fiction that blends horror, fantasy, and science fiction.
The true weird tale has something more than secret murder, bloody bones, or a sheeted form clanking chains according to rule. A certain atmosphere of breathless and unexplainable dread of outer, unknown forces must be present; and there must be a hint, expressed with a seriousness and portentousness becoming its subject, of that most terrible conception of the human brain--a malign and particular suspension or defeat of those fixed laws of Nature which are our only safeguard against the assaults of chaos and the daemons of unplumbed space.
Although Lovecraft was one of the few early 20th-century writers to describe their work as weird fiction, the term has enjoyed a contemporary revival in New Weird fiction. China Miéville often uses "weird fiction" as a way to describe his quasi science fiction and unconventional fantasy. Many horror writers have situated themselves within the tradition of weird fiction, including Clive Barker, who describes his fiction as fantastique, and Ramsey Campbell, whose work is deeply influenced by Lovecraft.
