An optician is read as help to see clearly again. Dream books connect the figure to a fresh perspective, to adjusting your view and to finding the right lens on a situation.
Has this come up in your dreams before? What was going on in your life then?
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.
