Crossing a border is read as a step into a new phase or territory of life. Dream books link it to transition, and to the permission you give yourself to move on.
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.
