A poem in a dream is read as feeling put into its most concentrated form. Dream books suggest paying attention to the words, which often hold what plain speech could not.
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.
