    I have a hard time believing those stories though.
    If a sudden blood pressure drop is enough to make someone fall unconscious immediately with blood still flowing to the brain, then a full blood pressure drop with no blood flowing to the brain should have the same effect.
    If I had to guess, eye and mouth movements are probably from the nerves going crazy after being severed at the brain stem.
