Jon has in several interviews said that not even he knows what his lyrics mean or are about, but feels that he learns it on an emotional or spiritual or intuitive level as the years go by and he sings the songs.
So any interpretation is as good as any other. Anyones best shot is as valid as anyone else's.
As for me, I often feel (and love) that he is just using beautiful yet random words in interesting phrases. To me, he is simply just painting with words and using his voice as any other instrument. Nobody would dream of asking what Rick Wakeman meant by that solo or this chords or same of Steve Howies phrasing, guitar timbre or choice of pedals, etc. I see Jons lyrics as just beautiful sound combinations he makes with his mouth that can tickle my ears, heart and mind same as any good instrumentalist.
Honestly, read the lyrics and you will find that not only are they abstract to the extreme (to put it positively) but actually often even lack any grammatical coherence. And I absolutely love it! He is my favorite lyricist for those reasons: it is just beautiful.
But guess away. It's everyones right and can be a good exercise.
