I felt a funeral Lyrics

I felt a funeral in my brain
And mourners to and fro
Kept treading, treading 'til
It seemed that sense was breaking through

And when they all were seated
A service like a drum
Kept beating, beating 'til
I thought my mind was going numb

And then I heard them lift a box
And creak across my soul
With those same boots of lead again
Then space began to toll

As all the heavens were a bell
And being but an ear
And I and silence, some strange race
Wrecked, solitary, here

And then a plank in reason broke
And I dropped down and down
And hit a world at every plunge
And finished knowing then

I felt a funeral in my brain
And mourners to and fro
Kept treading, treading 'til
It seemed that sense was breaking through
