Skimming over water behind a boat is read as riding on someone else’s momentum while keeping your own balance. Water is feeling, so it also speaks of staying on top of emotions.

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.
