1970s 'giallo' Euro-horror written and directed by Lucio Fulci. Florinda Bolkan stars as Carol Hammond, a troubled young woman who experiences a series of bizarre sexual dreams in which she indulges in perverse sexual activities with her neighbour Julia Durer (Anita Strindberg). When Julia later turns up dead, brutally stabbed in her apartment in exactly the way it happened in Carol's dream, Carol must try to distinguish between dreams and reality in order to solve the crime and prove that she is not the murderer - despite the fact that all the evidence points to her.
