A small wound spreading through everything is read as a problem left untended that has started to affect the whole of life. It is a symbol of neglect, not a medical warning.
Where in your waking life have you met something like this lately?
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.
