Feeling guilty for surviving is read as grief tangled with responsibility. Dream books see it as a heart trying to make sense of uneven loss, and as a need for self-forgiveness.
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.
