A moat is a ring of water between you and the world. Dream books read it as emotional distance used for protection, and crossing it as letting someone get closer.
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.
