Spawning fish swim against the current to begin new life, so dream books read the scene as effort spent for the sake of something that will outlast you.
Where in your waking life have you met something like this lately?
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.
