Walking a tightrope is read as a situation with very little margin for error, where every step needs attention. Dream books link it to delicate decisions and to keeping composure under watch.
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.
