Though many of the stories are written by science fiction, fantasy, and horror writers and contain fantastic or supernatural elements, "Interfictions" is not a genre anthology. "...interstitial fiction mixes and matches these precepts—ghost stories, science fiction, nursery rhymes, detective story, whatever may be handy—as part of a variegated prism to focus on the psychology of existence even while bending its collectively recognized state. ...each 'interfiction' shares this sense of disjointed narrative, but in very different ways that do not lend themselves to easy genre categorization."
