Good manners are read as the rules that make living together smooth. In dreams they point to how much you adapt to fit in, and whether that feels like respect or like a costume.
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.
