Abraham Lincoln: rêve prémonitoire?

Premier topo d'une série de quatre d'Errol Morris dans le New York Times. Lincoln a-t-il "rêvé" sa mort? Comment gérer les témoignages et les sources?

 Confidences de Lincoln à un garde du corps:

 “There I met with a sickening surprise. Before me was a catafalque, on which rested a corpse wrapped in funeral vestments. Around it were stationed soldiers who were acting as guards; and there was a throng of people, gazing mournfully upon the corpse, whose face was covered, others weeping pitifully. ‘Who is dead in the White House?’ I demanded of one of the soldiers, ‘The President,’ was his answer; ‘he was killed by an assassin.’ Then came a loud burst of grief from the crowd, which awoke me from my dream. I slept no more that night; and although it was only a dream, I have been strangely annoyed by it ever since.”
