An ice storm coats everything in a heavy, brittle shell, so dream books read it as a situation frozen in place and strained under its own weight. It stands for coldness that makes things fragile.
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.
