An atlas is read as an overview of possibilities — places, paths and directions laid out at once. It speaks of planning, wanderlust and the wish to see where you stand.
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.
