The different accidents of life are not so changeable as the feelings of human nature. 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, the beauty of the dream vanished, and breathless horror and disgust filled my heart.

– Mary Shelley

Frankenstein, Chapter 5. When the creature awakens and the result of his bid to create life turns out to be monstrous, Victor realizes that he made a mistake and his dream to be god-like should have remained a dream.
