The wallaby is a smaller, nimbler relative of the kangaroo. Dream books read it as quick progress on a modest scale and as caution that keeps close to cover.
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.
