The quote from Denis Johnson's "Train Dreams" illustrates the profound impact of a first kiss on the protagonist. It suggests that this intimate moment acts as a catalyst, transforming his perception and direction in life. The imagery of falling down a hole conveys a sense of unexpected change, as if the kiss unlocks new emotions and possibilities that he previously overlooked.

This newfound understanding of love leads him to feel aligned with himself, as metaphorically, he turns around and starts heading downstream. The reference to the wrong direction emphasizes a sense of struggle and confusion, hinting at the complexity of human relationships and the pivotal moments that redefine our paths. In essence, the kiss symbolizes both awakening and the potential for growth.
