can someone 'splain me "ahead by a century"?

[footfootfoot]

I like this tune, and I'm not sure of what the lyrics mean. I get the feel for the song from the music and the phrasing. But the words leave a little of a hole for me.

Any eye deers?

Ahead by a Century *
* First we'd climb a tree
and maybe then we'd talk
or sit silently
and listen to our thoughts
with illusions of someday
casting a golden light
no dresss rehersal,
this is our life
that's where the hornet stung me
and I had a feverish dream
with revenge and doubt
tonight, we smoke them out
You are ahead by a century
Stare in the morning shroud
and then the day began
I tilted your cloud,
you tilted my hand
rain falls in real time
and rain fell through the night
no dress rehearsal, this is our life
That's when the hornet stung me
and I had a serious dream
with revenge and doubt
tonight, we smoked them out
You are ahead by a century
but this is our life
and disappointing you's gettin'
me down
