If you get decapitated (head chopped off), will you see your body as your head falls down before you die?

Ok, say you get your head chopped off, will you actually get to watch your body as your head falls to the ground? This would mean you're still alive for a few seconds so you actually see as your head is falling. Then the last thing you see before death is what it looks like to have your head on the ground and your body standing next to you. Is this possible?
