Perfume is read as attraction, memory and the impression you leave behind. A familiar scent in a dream is often taken as longing for a person or a moment.
When this appeared in your dream, what were you feeling?
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.
