A war god is read as raw drive, aggression and the will to fight for something. In a dream it reflects conflict, courage or anger that is asking to be channelled wisely.

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.
