The quote "We're on the cutting edge of reality itself. Right where it turns into a dream" from Denis Johnson's novel "Tree of Smoke" highlights a transition point between the tangible world and the realm of dreams. This suggests an exploration of perceptions and the complexities of human experience, particularly in times of conflict or upheaval. It raises questions about how reality and dreams influence our understanding of life and truth.

This intriguing perspective invites readers to reflect on their own experiences and the blurred lines between what is real and what is imagined. The novel, set against the backdrop of the Vietnam War, uses this theme to delve into the inner lives of its characters, illustrating how their realities might merge with their dreams and aspirations amidst chaos. Such ideas resonate widely, encouraging a deeper contemplation of the nature of existence.
