Hyrum Grant's visionary experience of his father's condition

“One night he was very bad. He imagined a great, black man was trying to place iron bands upon him; but he thought that his eldest son Hyrum came to his rescue. At that time Hyrum was in Kansas City, Mo., at school, but we learned afterward. that at the time my father thought he was present, Hyrum had been fasting forty-eight hours, and was shown’ in a vision, or dream, the exact condition of my father, and seemed to be at his bedside. — Millennial Star 67:19”
