When the ground opens in a crack, dream books read it as a split in something that felt solid — a relationship, a plan, a belief. It also stands for what was buried coming up to the light.
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.
