The fairy godmother stands for unexpected help and a wish granted at the right moment. Dream books read the figure as hope and kindly guidance, not as a promise of anything.
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.
