Once upon a time, my husband was an atheist. Then he had a heart attack, and was healed by prayer. He both converted and went to the hospital to find out what happen. They told him, his heart itself was healthy, but he needed a quintuple bipass.
When he came home from the hospital, he had a dream. He dragged himself out of bed to the office and wrote down, from the dream, an outline for an entire novel. Almost twelve years later, he wrote the entire novel in five weeks. (Normally writing a novel takes him six months at least.)
Today, that novel is now available: Iron Chamber of Memories.
