I am going to have nightmares for weeks. I found this an seriously was about to puke due to how creepy it was.
Here is the story of Edward Mordrake, a man with two faces. (Voldemort (but so much creepier)):
Edward Mordrake was reportedly a 19th century aristocrat in England. He supposedly had an extra face on the back of his head, which could neither eat nor speak, although it could laugh or cry. Edward begged doctors to have his “demon head” removed, because, supposedly, it whispered horrible things to him at night, but no doctor would attempt it. He committed suicide at the age of 23. via imrimri.tumblr.com
This is not a real picture (there are none) but an artist's representation.
