Anybdy? Whts the meaning of these lines?

1.Waiting for a letter, only to discover that I\'m not the same

  1. sold it to the trees

3.underneath the harbour, waiting for the sun to settle down

4.I own it to your dreams, they always seem to bring me round

5.waiting at the harbour there is only water to be talking to

6.sitting round staring at the ceiling

AND WHATS IT GOT TO DO WITH \'SOFA\'?
