Someone said, "Song-Writing is re-writing."
We get 'inspiration' and run with it.
Once the basic concept is 'written', in our heads, if not down on paper, we can 'craft' it, adding or subtracting what 'inspiration' got.
I do 'editing' as I write, getting that first Line that Hooks my interest, maybe going on to more Lines before I think of something I judge to be better for that first 'inspired' Line. Throughout the process I may try variations on the Line, different words, getting the Rhythm of the Prosody to fit the guitar work and Melodic delivery 'right'.
Nothing is written in stone. However... once I do put it down on paper it becomes harder to rewrite. And once I play it for anyone else I feel locked in. I have to break out. Fortunately, years of experience have taught me how free I am to do whatever I want with a Song.
I didn't get any sense of death. I thought it was a person who appeared in a dream, and the dreamer fell in love, to a rational not-crazy-at-all degree, and simply hopes to see the person again in the dream, and hopes she appears in reality.
Rob's Lines about 'recognizing her eyes, in the waking light'.
Indulging in fantasy is quite entertaining. Pondering death and longing for the lost loved one, a whole different direction.
I think most people can 'relate' to either concept, but which one do you want them to relate to?
I go with the fantasy, the 'dream' and 'hope' of encountering the dream personality, in the Same Time, Same Dream, and the fantasy that he could actually meet her in life. That love at first sight concept is real, for some people, and fantasy of possibility, and dreaming, are natural to the Human mind.
All kinds of positive vibration to go with.

There will always be another song to be written. Someone will write it. Why not you? www.garyeandrews.com
