What motivates people to organize communal living themselves? What ideals are behind it, how do they finance themselves, and how does life in a community work? Based on six self-managed residential buildings in Austria from the past 40 years, the documentary film "Der Stoff, aus dem Träume sind" (The Stuff Dreams Are Made Of) sets out to find answers. Filmmakers Lotte Schreiber and Michael Rieper tell these six stories by staying very close to the protagonists.
