In the game of Dawn Card-Castles, fifty-two playing cards are stacked up into a castle in a draught-free space: the player can determine the dreams of the next night if he awakes before the castle collapses. Those players who wish to dream of Romance build their castle with the seven of hearts. Peter Greenaway
