A lens focuses or distorts what is seen, and dream tradition reads it as perspective — how you are looking at a situation. A cracked or blurred lens points to a view that needs adjusting.
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.
