Cut one head and two grow back: the hydra is read as a problem that multiplies the more bluntly it is fought. Dream books take it as a nudge to change the approach rather than strike harder.
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.
