A class photo is read as a frozen moment of belonging to a group. Looking for your own face in it points to questions about where you fit, then and now.
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.
