Great seers such as Edgar Cayce saw things many years in advance. In fact, he predicted many events that occurred even AFTER his own lifetime - after his own death.
Abraham Lincoln was famous for his interest in psychics and had a psychic advisor during his presidency (he also held seances in the White house). Lincoln had a foreboding the Day before his assassination of his own death and saw the funeral procession for him in the white house beforehand in a vivid dream that he recorded in his personal journal.
