Blushing is read as embarrassment, attraction or being caught off guard. It mirrors feelings showing on the surface when you would rather keep them private.
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.
