Living a double life is read as parts of yourself you keep hidden from others. Dream books link it to protecting something precious, or to the strain of keeping up appearances.
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.
