Stepping stones are read as progress made one careful step at a time, each one a small achievement. Dream books link them to balance and to trusting the next foothold.
When this appeared in your dream, what were you feeling?
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.
