In Faulkner's "The Sound and the Fury," the imagery of the shadow of the bridge highlights a sense of depth and mystery, suggesting an exploration of the unknown. The phrase conjures a sense of looking down into something that, although visible for some distance, remains elusive and ultimately out of reach, much like certain memories or emotions that linger beneath the surface.

The metaphor of a leaf in water illustrates the passage of time and the inevitable decay of connections. As the leaf disintegrates, its fibers float gently, signifying that former ties can unravel and fade away, despite their earlier intimacy. This reflects the themes of memory and loss, emphasizing how relationships can change and drift apart over time.
