Definition of Foreshadowing
The Metamorphosis opens with an imagery-laden description of Gregor's body as an insect:
He was lying on his hard, as it were armor-plated, back and when he lifted his head a little he could see his dome-like brown belly divided into stiff arched segments on top of which the bed quilt could hardly keep in position and was about to slide off completely. His numerous legs, which were pitifully thin compared to the rest of his bulk, waved helplessly before his eyes.
Kafka uses uses imagery to describe Gregor's waning sight in Section 2:
Unlock with LitCharts A+For in reality day by day things that were even a little way off were growing dimmer to his sight; the hospital across the street, which he used to execrate for being all too often before his eyes, was now quite beyond his range of vision, and if he had not known that he lived in Charlotte Street, a quiet street but still a city street, he might have believed that his window gave on a desert waste where gray sky and gray land blended indistinguishably into each other.
