This isn't really a commonly used expression. I could see it being used in poetry or literature, but it isn't something you would hear in conversation (unless you're talking to someone very poetic with an odd way of speaking).
In a book, you may see it used like: "She danced on the edge of death. Her heart stopped and was brought back by the doctors again and again throughout the night, but it never stopped for good. And in the morning, she opened her eyes."
