A customer in a dream is read as demands and exchange — what others want from you, or what you want from them. Tradition sees it as service, value and fair dealing.
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.
