A blizzard stands for confusion and isolation — so much coming at once that nothing can be seen clearly. Dream books read sheltering from it as the need to wait for calmer conditions.

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.
