Books - In our daily life, books are a source of information and a place to gain knowledge. They can be inspirational, and their messages are sometimes so strong that they change our lives. The books in our dreams can represent our memories, learned understanding, ideas, or viewpoints. They can alert us to the fact that we have something new to learn and that we should spend time on mastering new tasks. Pay attention to what kind of book you are seeing in your dream and its purpose in the larger context of the dream. Also, note reading any passages or specific messages from the book. At times the book may be pointing to new themes or purposes in your life. Pay attention! The unconscious mind is constantly making attempts to communicate with the conscious in such ways that the dreamer will recognize it without panic or denial. Superstition-based dream interpretations say that if you are dreaming of books, you can be assured of slow but steady progress in your life.
