A coming-of-age rite is read as stepping into a fuller version of yourself. Dream books link it to new responsibility and to leaving an earlier stage behind with some ceremony.
Where in your waking life have you met something like this lately?
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.
