"There was no reflection of him in the mirror!" writes Jonathan Harker in Dracula by Bram Stoker. It's said that mirrors reflect the soul, which is the reason why vampires, who don't have souls, traditionally don't show up in them. Most movie versions of Dracula have a scene in which the Count casts no reflection. In the opening segment of the portmanteau movie The Vault of Horror, Daniel Massey discovers he's the sole diner visible in a restaurant mirror, but two of the best mirror moments are in this horror-comedy by Roman Polanski (who had already inserted an early example of the "mirror scare" into Repulsion). The first is in a scene between the vampire hunter's assistant (played by the director himself) and the Count's gay son; the second takes place at the climax of the eponymous dance.
