In Richard Brautigan's "Trout Fishing in America," the imagery evokes a surreal yet serene experience of walking home at night. The phrase "glass whiskers of the houses" suggests a whimsical quality, where the architecture appears to shimmer and blend with the environment. This reflection enhances the beauty of the night, transforming everyday scenery into something magical.

The mention of "downward rushing waterfalls of night" conveys a sense of time and movement, illustrating how the darkness envelops everything around. This creates an almost fluid experience, where nightfall descends like cascading water, emphasizing the peaceful yet profound nature of the evening stroll. Overall, Brautigan captures the interplay between the ordinary and extraordinary through vivid and imaginative language.
