Early life
Yumeno was born in Fukuoka city, Fukuoka prefecture as Sugiyama Naoki. His father, Sugiyama Shigemaru, was a major figure in the pre-war ultranationalist organization, the Genyōsha. After graduating from Shuyukan he attended the Literature Department at Keio University, but dropped out and was adapted for a 1988 movie directed by Toshio Matsumoto and starring Shijaku Katsura II, Hideo Murota, and Yōji Matsuda.
Dogra Magra exemplifies modern Japanese avant-garde gothic literature. In the story, the protagonist/narrator wakes up in a hospital with amnesia. He finds out that he was the subject of an experiment by a now-dead psychiatrist, and the doctors are working to bring back his memories. It is not clear whether he was a psychotic killer or the victim of a strange psychological experiment, but it is told that he killed his mother and wife and that he inherited his psychotic tendencies from an insane ancestor. The novel is strongly influenced by Freudian psychoanalysis and, through Yumeno's contacts there, provides considerable historical insight into the development of the study of psychoanalysis at Kyushu Imperial University.
