A weapon that will not work at the crucial moment is read as feeling powerless to defend yourself or make yourself heard. Tradition links it to effort that fails just when it counts.
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.
