A last breath is read as the precise moment of letting go. Dream books see it as an ending reached at last, often with a sense of release rather than dread.
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.
