The Mirror House

The Mirror House is a ranch style haunted house presumably located in Northern California that has been opened for tours. Each room of the Mirror House has a floor to ceiling mirror - the mirrors increase the deeper you travel into the house, some rooms even having floors and ceilings that are mirrored. In the center of the house is an octagonal room that is entirely covered in mirrors. It is here that Anna encounters a horrific doppelgänger.
