Three days before his death, Abraham Lincoln told a group of close friends about a haunting nightmare in which he was told that he had been assassinated. Lincoln's dream would prove to be prophetic on the night of April 14, 1865, five days after the end of the Civil War.  While attending the popular comedy Our American Cousin with his wife and two young friends, Lincoln was shot in the back of the head by John Wilkes Booth, a Confederate sympathizer who also happened to be the nation's most famous actor. It is often referred to as the shot heard around the world.
