Sweeping is read as clearing away old matters to make a fresh start. Folk tradition also takes it as the wish to put a home, or a life, back in order.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
