Speaking and not being heard is read as a fear of being overlooked or not mattering. Dream books see in it a call to give your own voice more room.
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.
