Book excerpt: Nathaniel Wallace’s Scanning the Hypnoglyph chronicles a contemporary genre that exploits sleep’s evocative dimensions. While dreams, sleeping nudes, and other facets of the dormant state were popular with artists of the early twentieth century (and long before), sleep experiences have given rise to an even wider range of postmodern artwork. Scanning the Hypnoglyph first assesses the modernist framework wherein the sleeping subject typically enjoys firm psychic grounding. As postmodernism begins, subjective space is fragmented, the representation of sleep reflecting the trend. Among other topics, this book demonstrates how portrayals of dormant individuals can reveal imprints of the self. Gender issues are taken up as well. “Mainstream,” heterosexual representations are considered along with depictions of gay, lesbian, and androgynous sleepers.
