The green flash at the last instant of sunset is a rare sight, so dream tradition reads it as a fleeting insight that only patience lets you catch. It speaks of watching closely for the small, precious moment.
Has this come up in your dreams before? What was going on in your life then?
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.
