Why might an author use an illusion in writing would the answer be to add layers of meaning to make the reading more personal to add a figure of speech, or to make the reading more difficult?

An author might use an illusion in writing for various reasons. While adding layers of meaning and making the reading more personal are potential objectives, these are not the only reasons. Another common purpose of using illusions in writing is to enhance the imagery or descriptive quality of the text. Illusions can create vivid or imaginative images in the reader's mind, making the writing more engaging and memorable.

Furthermore, using illusions can evoke emotions or connect the reader to cultural references or shared knowledge. They can serve as a way to communicate complex ideas or abstract concepts in a more accessible manner. By employing illusions, the author may also be aiming to create an atmosphere or tone that complements or enhances the overall theme or message of the writing.

While illusions can add depth and creativity to the text, it is essential for the author to strike a balance. Overuse of illusions or excessively obfuscating the writing can make it difficult for readers to understand, potentially deterring them from engaging with the text. Therefore, the primary intention of using illusions is not typically to make the reading more difficult, but rather to enhance its aesthetic qualities and communicative power.
