Mittens are read as warmth, care and the cosiness of childhood winters. Because they make fine work clumsy, they can also stand for feeling protected but limited.
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.
