Bedtime Stories: Bridges(1977)

"As if pictures could think! Einschlafgeschichten doesn't really speak of bridges or railroads but rather of two girls filling the space between daytime and dreamtime with a poetic game, an endless game, a game with no end. A game which can fade out without becoming fragmentary. "Are you asleep?", one of them asks at the end of a clip – and the final shot is of the two, asleep; the game is over. The girls are played by Lara and Anna, Farocki's daughters."
