Trust is read as willingness to rely on another or on yourself. Dream books link it to safety and openness, and to questions about who in your life has earned that confidence.
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.
