The mirror is the symbol of self-image. Dream books read what you see in it — clear, strange or missing — as how you see yourself right now. A face that is older, younger or not your own points to a changing sense of identity, while no reflection at all is traditionally read as feeling unseen or unsure who you are. A broken mirror is read as a self-image that has been shaken, not as bad luck. Looking calmly into a clear mirror is taken as honesty and acceptance.
Where in your waking life have you met something like this lately?
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.
