A thesis can only be written after a student has come up with the "bright idea" that will inspire and direct the essay they will write. What is needed here from you is a bright idea about the dream motif found in 1984. Once you get your bright idea, based on the themes, the characters, the conflicts or the structure or other devices of the novel, then you can write a thesis statement that will set forth the brief statement of your idea and the route through which you intend to prove it. For instance, if you decide that time is a critical factor to understanding the dream motif, your thesis would include that.
- Example: Time is the critical factor that unifies all the dreams and that leads to a unified thematic meaning of the dream motif.
Caution: This is purely hypothetical and not in the least verified: do not use this sentence as a thesis.
Years ago--how long was it? Seven years it must be--he had dreamed that he was walking through a pitch-dark room. And someone sitting to one side of him had said as he passed: 'We shall meet in the place where there is no darkness.'
