In Slavic mythology, a rusalka was a female ghost, water nymph, succubus or mermaid-like demon that dwelled in a waterway. According to most traditions, the rusalki were fish-women, who lived at the bottom of rivers. In the middle of the night, they would walk out to the bank and dance in meadows. If they saw handsome men, they would fascinate them with songs and dancing, mesmerize them, then lead the man away to the river floor to his death. The stories about rusalki have parallels with those of Hylas and the Nymphs, the Germanic Nix, the Irish Banshee, the Scottish Bean Nighe and the Romanian Iele. See Slavic fairies for similar creatures. In most versions, the rusalka is an unquiet dead being, associated with the unclean force". According to Zelenin, people who die violently and before their time, such as young women who commit suicide because they have been jilted by their lovers, or unmarried women who are pregnant, must live out their designated time on earth as a spirit."
