Miss Caroline Bingley dreamt of being Mrs. Darcy, every night from their first introduction until the night she attended some dreadful assembly in some hideous little village full of savages. That night, for the first time out of many, she dreamt of becoming the spinster aunt to her brother's ten children, teaching them to dress and behave very ill indeed.
No matter how many times she attempted to have Mr. Darcy make a lifelong commitment to her, by wiles, by force, by any means, she never succeeded. No matter how many times she willed herself to focus on being Mrs. Darcy, again and again, her nighttime premonitions never returned to that state of bliss.
