A boat carries you across feeling. Tradition reads a steady boat as coping well with emotion, and a leaking or drifting one as feeling at its mercy. Rowing yourself is taken as effort and self-reliance, while being carried by sail or current points to trusting the flow of events. A capsizing boat is read as being overwhelmed for a moment, not as a forecast. A small boat on a vast sea suggests feeling small next to a big change, and reaching the shore is read as arriving somewhere solid again.
When this appeared in your dream, what were you feeling?
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.
