The moon rover stands for careful exploration of unfamiliar terrain, far from home. Dream books read it as curiosity about a strange new part of life, approached slowly and with a lot of preparation.
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.
