A gold star stands for praise and approval, the simple joy of being told you did well. It is read as a wish for recognition, or for more kindness toward yourself.
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.
