Being beaten in a dream is read as feeling overpowered or worn down by circumstances, and tradition looks at who is doing it to see what pressure is meant.

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.
