Did you know that the ghost of Abraham Lincoln has been haunting the White House?
Now ghosts are a tricky subject mainly because most people do not believe in the supernatural, but try telling that to Queen Wilhelmina from the Netherlands.
Queen Wilhelmina was a guest at the White House around the time FDR was being administrated as president. She claimed that she was awakened one night by the sound of someone knocking on her door. When she opened it, she saw an apparition of Abraham Lincoln standing in the hallway. The Queen fainted and when she recovered consciousness, she was laying on the floor and Lincoln had vanished.
