Beyond the Wall of Sleep is a collection of fantasy, horror and science fiction short stories, poems and essays by American author H. P. Lovecraft.

Although the story and poetry selections have appeared in other Lovecraft collections, Beyond the Wall of Sleep has never been reprinted in its original form.

[1] 'Beyond the Wall of Sleep' is a song on the debut album of the influential Heavy Metal band Black Sabbath.

Without the coloring excitement of narrative suspense and climax his language seems thin and obvious, getting most of its effects by the hypnotic repetition or judicious timing of adjectives like 'slimy,' 'nameless,' or 'loathsome.

'"[2] E. F. Bleiler described Beyond as "really an afterthought volume", commenting that "The fiction is almost all minor, although The Case of Charles Dexter Ward, despite its being strangely tired and routine, has interesting concepts and good moments".
