Weeping blood is an old image from sacred art and legend, read as grief that runs as deep as life itself. Dream books treat it as sorrow too heavy for ordinary tears.
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.
