I feel like figurative language is incredibly vital in a work of literature. For me personally it adds to my interest while reading. It keeps me wondering and constantly trying to figure things out. Whether or not things should be taken literally or if one thing represents another. The possibilitys are endless and in some cases the true 100 percent meaning of things could only be interpreted by the writer.
You have to be aware when reading things full of metaphorical meanings and such. For most things arent what they are clearly stated, you have to be creative and keep an open mind. Do these things and understanding these works that consist of such will become more of an entertainment than an assignment. See things for what they are not.
