Rolling up your sleeves is a classic picture of readiness to work. Tradition reads it as commitment — deciding to dig in rather than watch from the side.
Has this come up in your dreams before? What was going on in your life then?
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.
