伊藤潤二恐怖漫画コレクション トンネル奇譚

The fourteenth volume in the Kyoufu Manga Collection run leans toward science-fiction horror, opening with Long Dream, in which a patient's dreams stretch longer and longer with each hospital visit until his doctor realizes what's happening to him. It's followed by the title story about a tunnel that leads travelers somewhere they shouldn't go, plus The Bronze Statue, Floaters, and Blood Sickness of the White Sands Village, all built around outbreaks and phenomena doctors and scientists can't explain.
