It Follows (2014)

Jay has her first sexual encounter with her boyfriend, but she discovers that he has passed on a fearsome curse to free himself from the spirits that haunt him. Now Jay is the one who is harassed by an entity that takes various forms and gradually approaches her with the intention to kill her. Jay and his friends try not to lose their sanity as they find a way to break the curse. A visually austere but utterly terrifying horror film based on the fear of the unknown, with a brilliant soundtrack.
