A film crew stands for the many helpers working behind the scenes of a single performance. Dream books read it as teamwork, or as being watched closely while you try to get things right.
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.
