Lying down to make a snow angel is read as a return to childlike trust and the wish to leave a gentle mark. It speaks of innocence and of a moment of stillness enjoyed for its own sake.

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.
