Since ancient times mirrors or other reflective surfaces, have been considered portals to the unseen realms of spirits. Spirits have been summand through mirrors for ages. They also could be used to see the past or the future. Standing water whether it be natural or in a bowl was used like a mirror. Other items used were polished metals and crystal balls.
In folklore mirrors are soul stealers, they have the power to rip the soul right out of bodies. It is also said that demons can enter through mirrors. Actually any spirit can use a mirror as a doorway into our world. If you see your reflection in a mirror in a room that someone has died in, it is considered an omen of death. Mirrors are said to hold souls if you would break a mirror the soul is also broken.
