A police station is read as rules, order and the wish for protection, or as worry about being held responsible. Dream books ask whether you went there for help or were brought in.
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.
