In "Lie Down in Darkness" by William Styron, the protagonist reflects on the power of focusing solely on the present moment. He considers that by concentrating on the immediate second, he might be able to alter the course of events, such as the arrival of an impending train, which symbolizes an unavoidable change or challenge. This line conveys a sense of anxiety and a desire to escape the future.

The thought of concentrating on the here and now, alongside imagery of water, suggests a longing for peace amid turmoil. It highlights the struggle between the weight of impending realities and the comfort of living in the moment, ultimately pointing to a deeper existential reflection on how individuals cope with anxiety about the future.
