Rowing is read as steady, personal effort to move through feeling or circumstance. Dream books ask whether you rowed alone or with others, and with the current or against it.
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.
