How does Lauren Oliver use imagery in Before I Fall?

Imagery:

"Maybe when you die time folds in on you, and you bounce around inside this little bubble forever...It's not what I imagined death would be like - not what I imagined would come afterward - but then again it's not like there's anyone around to tell you" (p. 96).

"Isn't it kind of weird how that stuff happens? How everything spirals out from everything else? It's like a web, you know? Everything's connected."
