Turning against yourself in a dream is read symbolically, as old pain pointed inward and asking to be seen with more kindness. If such feelings stay with you while awake, talking to someone you trust can help carry them.
When this appeared in your dream, what were you feeling?
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.
