Books thrown on a fire are traditionally read as fear of being silenced, or of ideas being erased before they are heard. Some dream books also see in it a harsh break with old beliefs you no longer want to carry.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
