An auditorium is built for listening and being heard. Dream books read it as the wish to be understood by many, or the nerves of speaking when every seat is turned toward you.
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.
