The golden ratio turns up in shells, flowers and much-admired art, so it stands for natural beauty and proportion. In a dream it is read as a longing for things to fit together just right.

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.
