The fishing boat stands for patient work at the edge of the unknown, casting out and waiting to see what comes up. Folk tradition reads it as making a living from your own effort, and as drawing ideas up from the deep.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
