Arthur Tress is a photographer. During the 60s and 70s, he asked children to describe their nightmares to him. Then he recreated those dreams in carefully staged photographs. Tress called the series Daymares. Jen Carlson describes it in The Gothamist:
Tress spoke with children about their dreams—often nightmares that involved falling, monsters, that buried alive scenario—and would then photograph them experiencing it in a safe, staged setting. The images he captured are intensely surreal at times, and turn the landscape of New York City (and eventually other areas) into a fantastic nightmare and apocalyptic wonderland.
