The famous brain surgeon, Dr. Ben Carson, a presidential contender, recounted the time at Yale when he was failing chemistry and begged the Lord for help, then fell asleep. He had planned to pull an “all-nighter.” He was desperate.

As he told a national prayer breakfast, “You can’t be a pre-med and fail in chemistry.” He prayed, saying, “Lord, medicine is the only thing I ever wanted to do… Would you please tell me what is it you really want me to do?” In his sleep came a dream and in the dream he was alone in an auditorium and a “nebulous figure” was writing chemistry problems on a blackboard.

“When I went to take the test the next morning, it was like The Twilight Zone,” Dr. Carson recounted. “I opened that book and I recognized the first problem as one of the ones I dreamed about! And the next, and the next, and the next, and I aced the exam and got a good mark in chemistry.”
