A Cat in the Brain (1990)

Dr. Lucio Fulci is a director of splatter films. He stages a gestapo-orgy like it was any other movie scene. But he is influenced by these things more than he likes. He is hunted by bloody visions day by day. Is Fulci still normal? He asks a psychiatrist. He doesn't know that the psychiatrist has much bigger problems than Fulci himself. The psychiatrist then uses Fulci's visions for brutal murders in real life as an attempt to frame him.
