Walking on thin ice is the classic picture of risk, read as a situation where one wrong step could give way. Dream books link it to tension, caution and the need to tread carefully.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
