In certain books, like Lord of the Flies and the Road, the symbolism in the text is just as interesting as the words that are plainly put on the page. At times, the symbolism can almost alter the way that we are reading the book. Like, The Road is basically a story about a man and his son trying to find the coast. But with looking deeper into the book, it also has definite Biblical qualities to it. There are certain books in which the blue lamp is just the effing blue lamp. But in others, there is actual meaning to it. For people like me, it can be fun. But when it is taken too far, as in dissecting every single sentence of the book, it can actually be a bit of a downer. I can't give you a definite answer to this, but a book can just be a book!
