Bava Batra 73: The Esoteric Tales of a Jewish 'Sinbad'
Chapter 5! A new mishnah -- with a shift to a discussion of movable property, and what is included in their sales. For example, what is included in the sale of a ship (when the formality does not stipulate: "and everything that is within it"). Also, the voyages of Rabbah bar bar Chana -- which go beyond a traveler's account to mystical teachings/ experiences.
