This surreal and stunning collection of images are based on children's actual nightmares. It was shot in the 1960s and 70's, by American photographer Arthur Tress and is entitled the “Dream Collector”.
Full collection is featured on Tress's website.
In the artist's words:
“Dreams or nightmares were collected by conversations with children in schools, streets, or neighbourhood playgrounds. The children would be asked means of acting out their visions or to suggest ways of making them into visual actualities… These inventions often reflect the child’s inner life, his hopes and fears, as well as his symbolic transmutation of the external environment, his home or school, into manageable forms.”
