Pointing is read as directing attention — showing the way, or singling someone out. Dream books ask what was pointed at, since it marks what matters.
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.
