I felt a Funeral, in my Brain...

This is what a migraine feels like.

I felt a Funeral, in my Brain,
And Mourners to and fro
Kept treading — treading — till it seemed
That Sense was breaking through —

And when they all were seated,
A Service, like a Drum —
Kept beating — beating — till 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 —
