Haunted mirror

A haunted mirror was presumably a type of magical mirror "haunted" by some sort of spirit. The spirit (who might be a ghost) was presumably of some use to the owner of the Mirror, possibly in much the same way as a talking mirror, as Janus Galloglass, a mirror-maker in Diagon Alley, sold haunted mirrors among other products, implying that someone might want to purchase one.
