In Buddhist tradition the hungry ghost has a huge appetite and a tiny mouth, and dream books read it as craving that can never be satisfied. It points to a need that keeps asking for more than it receives.
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.
