A vow is a promise meant to last. Dreaming of one is read as commitment — kept, broken or still being weighed — and the bond it creates with another person or with 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.
