A body bag in a dream is not a sign of real death. Tradition reads it as something closed off and put away — an ending you are trying to contain.
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.
