3. Abe Lincoln et al
Abraham Lincoln was renowned for his belief in the supernatural, so it was no surprise that his spirit appeared numerous times around the White House to prove his point. Residents and guests have reported knocks on doors, stomping down corridors and mooching round rooms. First ladies Abigail Adams and Dolley Madison, plus Andrew Jackson, David Burns and little Willie Lincoln are also reported to haunt the most famous house in America.
