According to the recollection of one of his friends, Ward Hill Lamon, President Abraham Lincoln dreams on this night in 1865 of “the subdued sobs of mourners” and a corpse lying on a catafalque in the White House East Room. In the dream, Lincoln asked a soldier standing guard “Who is dead in the White House?” to which the soldier replied, “the President. He was killed by an assassin.” Lincoln woke up at that point.
On April 11, he told Lamon that the dream had “strangely annoyed” him ever since. Ten days after having the dream, Lincoln was shot dead by an assassin while attending the theater.
