One urban legend has that if you say “Bloody Mary” thirteen times in front of a candle lit mirror while brushing your hair, the revenging spirit of a woman will appear to disfigure you.
Argentinean writer Jose Louis Borges used the symbol of mirror to mean eternity, fantasy and imitation.
In Harry Potter and the Chamber of Secrets, a basilisk is a giant snake that kills people by looking in their eyes. Hermione was saved because she glimpsed at it through a mirror.
In early days, the mirror was actually a sheet of polished metal like silver and copper.
