How does Ann M. Martin use imagery in A Corner of the Universe?

Imagery:

"It was the kind of terrified look that reminds you that no matter how rational or grown up a person might seem, some part of him is absolutely sure - knows - that an evil other-world exists just outside of our regular everyday world. And that although we don't expect that world to collide with our calm, predictable one ... well, really, at any moment that is exactly what might happen."

"'Funeral days either pour down rain or pour forth sunshine. Nothing in between.'"
