In Polish mythology, the Wila are reputed in Poland and Lithuania to be the shape-shifting souls of the dead that were believed to visit the homes of their families. Peasants would lay flowers in the entrances to caves where they believed the Wila resided. Offerings for the Wila consist of ribbons, round cakes, vegetables, fresh fruit or other flowers left at sacred trees, fairy caves and wells. They are the female spirits that lived in the mountains, woods, and clouds that could shape-shift into horses, falcons, or swans also.
