A hall pass is read as permission to step out of the expected place for a while. Dream books link it to needing someone else’s approval before taking a small freedom.
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.
