There, on the Darkened Deathbed by John Masefield

This is pretty much what I think happens when we die, and unfortunately, what happens eventually after we die.

There, on the darkened deathbed, dies the brain
That flared three several times in seventy years;
It cannot lift the silly hand again,
Nor speak, nor sing, it neither sees nor hears.
And muffled mourners put it in the ground
And then go home, and in the earth it lies,
Too dark for vision and too deep for sound,
The million cells that made a good man wise.
Yet for a few short years an influence stirs,
A sense or wraith or essence of him dead,
Which makes insensate things its ministers
To those beloved, his spirit’s daily bread;
Then that, too, fades; in book or deed a spark
Lingers, then that, too, fades; then all is dark.
