Sol Branco (2015)

Eight-year-old Selena wakes up from a strange dream. She searches in a wooden trunk and finds her Snow White disguise. She is bored to death with her cousin in their vacation home in Portugal. While their older cousin tans in the garden, they sneak up and steal a donkey to go swimming at the dam. When they stop at a cemetery on the way, Selena sees the silhouette of an old lady in black, just like in her dream. She gets scared and then runs away, alone in the forest.
