梦如南筏
[mèng rú nán fá]
The literal translation is 'the dream raft of Nan'. Here 'Nan' can refer to 'south' or may also be a person's given name. The overall meaning is somewhat metaphorical - it could imply that the dreams are floating on something transient like rafts, hinting at the unpredictability yet hopeful nature of our aspirations.
