Skiing is read as speed and control on a slippery slope. Dream books see a smooth run as confidence, and a tumble as fear of going too fast.
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.
