Ears are read as listening, receptiveness and what reaches you from others. Dream books link them to news, gossip and the advice you take in.
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.
