The Student of Knowledge
Scholars have said that if a student of knowledge sees their ship go out onto land and sail on it, it may indicate their deviation in knowledge or argumentation towards innovation, hypocrisy, or immorality. The dream may also suggest the corruption of their craft, difficulty in livelihood, or breaking an oath with their wife.
