Coordinates pin a place down exactly, so they are read as the wish to know where you stand. Receiving a set in a dream suggests being guided toward something you need to find.
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.
