Lovecraft: Beyond the wall of sleep is a visual novel adaptation of the eponymous novel by Howard Philip Lovecraft. This adaptation is not a rewrite: it is verbatim the original work. However, it is illustrated with original drawings to pass down to the reader the greatness and the frightening atmosphere of the novel.

Beyond the wall of sleep is the story of an intern in a mental hospital who relates his experience with Joe Slater, an inmate who died at the facility a few weeks after being confined as a criminally insane murderer.
