What is an example of metaphor in the novel, All the Sinners Bleed?

Midway through the novel, Titus experiences a nightmare that serves as a clear metaphor for his own anxiety and fear. In the dream, Titus stands alone in a field, watching as “huge black clouds [roll] in like a tidal wave in the sky. And the wind is blowing through the dead stalks. And I’m all alone as the storm rolls in. Lighting and thunder and rain, but the rain hurts. It’s hot, boiling hot” (182). The hellacious scene in Titus’ dream reflects the terror that he feels in his waking life. As the Last Wolf terrorizes Charon County, Titus’ mind creates dreams that mirror his fear and sense of isolation.
