Help me pls

"Tell me... after my head is chopped off, will I still be able to hear, at least for a moment, the sound of my own blood gushing from the stump of my neck? That would be the pleasure to end all pleasures."

This is what a serial killer said when his head was about to be chopped off, and I've heard the same thing in an anime. I can't remember where so pls if you know tell me.
