Unwritten

This is a very difftent one for me. I really like it and hope you do to :) I had unwritten ( the song ) stuck in my head and I know it's not anything like it but this is what I got.

If this poem was unwritten, 
Are you really reading it?
Did someone really write it?
Or is it just your imagination 
If a tree falls in the middle of an empty forest does it make a sound?
Sound? What is sound?
Is it the essence of language? Or the lack of silence?
Silence, sharp deafening
Scary at times. Sometimes it's so quiet you wonder if anyone is there. Is anyone there? Is anyone anywhere?
Or is the whole world just unwritten?
