Is It Reasonable to Believe?

Lucy, the youngest of the children, ends up going into this wardrobe. She has an encounter with a fawn and tells her brothers and sisters about it. The further in she goes, the more their wardrobe chains. Some time later, edmund also follows after lucy into narnia. And he finds too that she was right all along. They go back to the professor's house, and lucy says, ah, i was right. Edmund knows too. In our age, i think we'd say that she's having mental health issues.
