In Franz Kafka's "The Metamorphosis," the protagonist undergoes a surreal transformation into an insect-like creature, leading to his profound alienation from family and society. This change strips him of his humanity, rendering him increasingly isolated and miserable as he struggles to adapt to his new existence. The narrative explores themes of identity, isolation, and the human condition through this drastic physical and emotional metamorphosis.

The poignant moment when the protagonist’s head sinks to the floor and his last breath escapes him symbolizes the culmination of his despair and loss of vitality. It serves as a powerful metaphor for the loss of self and the finality of his suffering. Kafka's work reflects the tragic consequences of societal detachment and the existential crises faced by individuals in a modern world devoid of compassion.
