A razor is a symbol of precision and sharp edges, read as cutting away what is unwanted to show a cleaner surface. Tradition also links it to a delicate situation where care is needed.
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.
