In chapter 4 of the book A Wrinkle in Time, Meg, Charles, and Calvin have entered some strange zone in the universe. The chapter opens with Meg feeling like she is falling through a black abyss. She can not feel her body or any of her limbs. It is almost as if they are not a part of her. She begins to feel a tingling sensation and starts to become aware that Charles and Calvin are somewhere near her, but it all seems to be about her senses.
Meg starts to feel a tingling sensation in her limbs, and she is aware that she is regaining her body and that it was probably with her all along. She finds the darkness going away and sees Calvin and Charles. She is in a strange place, a field that is sunlit. She had stepped through a wrinkle in time.
