Horror master Lovecraft (1890-1937) frequently used dreams in his tales of the supernatural to evoke fantastic worlds inconceivable to the conscious mind. He wrote many essays and poems early in his career, but gradually focussed on the writing of horror stories. S.T. Joshi is a freelance writer and editor. Among his critical and biographical studies are The Weird Tale (1990), and H.P. Lovecraft: A Life (1996). He has also edited Lovecraft's The Call of Cthulhu and Other Weird Stories for Penguin.
