The treehouse is a hideaway built above the adult world. It is read as a longing for a private refuge, for childhood imagination, or for a vantage point from which to see your life more clearly.
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.
