A union decided by others is read as a commitment that feels chosen for you rather than by you. Dream books link it to duty, family expectation and the question of how much room is left for your own wishes.
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.
