A strong sense of purpose is read as direction and a reason to keep moving. Dream books link it to a calling becoming clearer, or to the wish for work that 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.
