A bouquet is beauty gathered and handed to someone, so dream books read it as recognition, affection and a moment worth marking. Who gives it and who receives it is part of the reading.
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.
