A falling-out with someone close is read as a break in trust or understanding. Dream books link it to unresolved tension, and the wish to repair or finally let go.
Has this come up in your dreams before? What was going on in your life then?
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.
