In chapter 5 of Frankenstein, by Mary Wollstonecraft Shelley, Victor Frankenstein has a dream about Elizabeth that touches upon a former tragedy and foreshadows a greater tragedy to come. Before he falls asleep that night, he is recovering from the success of the "catastrophe" of bringing the creature to life.
I had worked hard for nearly two years, for the sole purpose of infusing life into an inanimate body. For this I had deprived myself of rest and health. I had desired it with an ardour that far exceeded moderation; but now that I had finished... breathless horror and disgust filled my heart.
Victor throws himself on his bed still fully clothed, and in time he falls asleep but is troubled by wild dreams.
At first, Victor's dream is pleasant. He dreamed about Elizabeth, his bride-to-be. She is "in the bloom of health," walking in the streets of Ingolstadt. Victor is delighted and surprised to see her. He hurries to embrace her, but as he kisses her, she turns into a corpse in his arms—specifically that of his deceased mother. Victor is thus recalling the most significant death in his life and at the same time he is presaging Elizabeth's death, which occurs on their wedding night.
Victor suddenly wakes in a cold sweat, and he barely has time to shake off his dream of death when he's confronted by the creature he has brought to life, who is standing at his bedside. The creature stares at him with what Victor described as "his watery eyes, that seemed almost of the same color as the dun-white sockets in which they were set."
In later chapters, the creature asks that Frankenstein make him a companion. When Frankenstein refrains from completing the task and ultimately decides against it, the creature says, "It is well. I go; but remember, I shall be with you on your wedding-night." In chapter 23, true to his word, the creature exacts revenge on Frankenstein by taking his companion from him: the creature kills Elizabeth on their wedding night. By this point, the significance of Frankenstein's dream in chapter 5 becomes clear. His sins have come full circle, and he has paid the greatest price.
