The dream boat is a symbol of travel and life, which has long been considered to have far-reaching significance, suggesting what is about to happen, and is a harbinger of luck and misfortune. The sunken ship you saw in your dream is not necessarily a bad omen, but also has the meaning of independence and freedom.
A few people fell into the water in the dream, which means that you look forward to the sense of security as a child and want to be protected. In your dream, you are actively saving people because you want to rely on others to spoil others.
