The dream seems to be suggesting that you keep in mind the issue of perspective. "What if", implies that things do not have to be seen as you might have originally seen them. Star Wars could be a cartoon, for example, as well as Lord of the Rings

Note that cartoons are meant to be laughed at, that is, they are meant to be taken very light-heartedly; not seriously. This idea could apply to both the movies you enjoy and to the books you read when younger. Note also that both the Star Wars and Lord of the Rings are favourites with younger children and teens. They are not meant to be an adult's "thing".
