In Albert Camus' "The Stranger," the narrator expresses a profound contemplation of mortality. Despite feeling a lack of imagination, he finds himself grappling with the concept of his own death, particularly the moment when his heart's rhythm comes to an end. This introspection highlights a struggle with the awareness of life's transience and the existential nature of human existence.

Through this reflection, the narrator reveals a deep existential loneliness and a search for meaning. The idea that he cannot vividly imagine the cessation of his heartbeat underscores his detachment from conventional emotional experiences, reflecting the themes of absurdism and alienation that permeate Camus' work.
