According to legend, doppelgangers (German for “double-walker”) are paranormal duplicates of a real person. They can manifest in a number of ways: You can see them out of the corner of your eye, meet them on a lonely road somewhere, or, chillingly, see them standing behind you when looking in a mirror.
They’re supposed to be BAD LUCK. They represent death. For example one night, Catherine The Great was lying down in bed when her servants said they just saw her sitting on the throne. She ordered the servants to shoot at the thing at her throne. Nothing happened but Catherine herself died shortly afterwards.
Queen Elizabeth also one day entered a room, only to see herself lying down in bed. She also died shortly afterwards. Even Abraham Lincoln took a moment to rest on his couch one evening. While lying there, he happened to glance in a mirror and saw his own visage—except that he had two faces.
A second Lincoln, pale and ghostly, was looking at him from the mirror, right next to his own face. Startled, he rose from the couch . . . and the doppelganger disappeared. He sat back down, only to see it again.
I hope you guys never come in contact with one !
