The hosts explore the superstition that breaking a mirror brings seven years of bad luck and trace its roots through ancient Greek and Roman beliefs about reflections and souls. They discuss how mirrors evolved from reflective water and polished metal to glass, why mirrors came to be associated with the soul, and where the "seven years" idea may have originated. The episode also covers various folk remedies for broken-mirror bad luck, and other mirror- and glass-related superstitions surrounding death, demons, and marriage rituals, tying it all to the Halloween season.
