10. Psychics believe that President Abraham Lincoln has never left the White House. For more than 70 years, presidents, first ladies, guests and members of the White House staff have claimed to have either seen Lincoln or felt his presence. Lincoln’s ghost was particularly prevalent during the administration of Franklin D. Roosevelt, as the country struggled through a devastating depression followed by a world war. The Netherlands’ Queen Wilhelmina was a guest at the White House during that period, and was awakened one night by a knock on her bedroom door. Upon opening the door, she saw the figure of Lincoln, top hat and all, standing in the hallway. The queen fainted, and upon recovering consciousness, she found herself lying on the floor. The apparition had vanished.
