Late one night in 1865, Abraham Lincoln had a discomfitting dream. Walking through the silent White House toward the sound of sobbing, he entered the East Room and was confronted by the sight of a catafalque (a coffin platform) covered in black, surrounded by a group of mourners. Lincoln proceeded to ask the guard on duty who had died. The man's reply? "The president."
[One week later, Lincoln, who had discussed the dream with several people, was assassinated by John Wilkes Booth. (Lincoln also had a dream on the eve of his election: While peering into a large mirror, he saw two distinct images of himself; one, much paler, superimposed upon the other. Lincoln's wife, told of the dream, interpreted it to mean that he would be elected to a second term but would not live through it.)]
[It may have interested Abraham Lincoln to learn that his son Todd was among the last people to visit each of the three presidents who were shot during his lifetime.]
