Celestite’s pale sky blue gives it its heavenly name, and it is read as serenity and a sense of being looked after. In dreams it often stands for calm after worry.

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.
