Finding yourself in a film is read as watching your life as if from outside, or playing a role for others. Dream books also see it as a wish for your story to matter.
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.
