A broadcast is read as a message sent out to many at once. Tradition asks whether you were the one speaking or the one tuning in, as a sign of how you share and receive.
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.
