Man has amnesia. Ceiling fans, room of mirrors, music notes flashback triggers. Resolution: was held captive in country house and I think framed for murder.

Fear in the Night (1947)
From Wikipedia synopsis:
Bank teller Vince Grayson (DeForest Kelley in his film debut) dreams that he stabs a man in an octagonal room of mirrors and locks the body in a closet. When he wakes up, he discovers marks on his throat, a strange key and a button in his pocket, and blood on his cuff. Cliff Herlihy (Paul Kelly), his police officer brother-in-law, tries to convince him it was just a dream.A few days later, while trying to find cover from the rain, the pair finds themselves taking shelter in the strange house from Vince's dream. They discover that the police found two bodies in the house, one in the mirrored room and one run over in the driveway. Mrs. Belknap, who was run over by a car, gave the police a description matching Vince before she died.
