In Denis Johnson's "Tree of Smoke," the nature of thought is explored as an intricate maze, illustrating how one idea can spiral into a multitude of others. This process reflects the complex and often convoluted workings of the mind, where thoughts can lead us far from our original intent, creating a labyrinthine journey of contemplation.

Ultimately, the passage suggests that the seemingly overwhelming nature of our thoughts can be deceptive. While we may feel trapped within these mental meanderings, the narrative concludes that these experiences are illusory, akin to dreams that we awaken from, emphasizing the transient nature of our mental struggles.
