It's called The Pepper's Ghost illusion. It's not technically mirrors, rather plate glass. The illusion of a ghost is created by an actor who remains out of sight from the audience in a room that is completely painted in black. The audience views a scene through a piece of plate glass such as a room with furniture, a dungeon, or any other type of scene. The actor is costumed in the black room with a beam of light focused directly on the actor which creates a reflection in the plate glass. When the audience views the scene through the plate glass, they see the reflection of the actor on the glass which provides the illusion of a transparent ghost.
