Hiller’s research into the cultural implications of dream analysis in her writings, as well as her artwork, can usefully extend Freud’s approach into the field of art. She categorises artists’ dream images into three categories: ‘the illustrative or descriptive, which picture or illustrate dream imagery of a more or less conventional kind, the documentary or artefactual, which attempt to achieve a kind of accurate reportage; and the evocative, which are meant to trigger off an experience similar to a dream’ (Art and Psychoanalysis by Maria Walsh).
