Many artists consider their dreams and nightmares as a source of inspiration. The intensity of what they see and feel during those fictive nightly worlds, the vivid images and unexpected events, free their minds and bring artistic creativity to light. Brigitte Holzinger’s scientific world is very close to the artistic one, no wonder then, that the books she has published do not prove only her profound knowledge in science, but are also thrilling to read. The same ambiance resulting of this balance between science and art is to be found in her documentary film « Eine Reise in die Nacht ». She has not only written the screenplay to it, but also co directed with Karina Ressler the entire film in order to set the harmony between the visuals and the scientific study of sleep, this fascinating topic we are all concerned of.
