IN THE EPISODE TITLED (DEATH BECOMES THEM), A CLASSMATE OF PHOEBE'S IS MURDERED BY ZANKOU. WHEN PHOEBE AND DARREL ARE IN THE CITY MORGUE, THEY ARE DISCUSSING ABOUT THE DECEASED, AND FROM A SIDE SHOT OF THE CORPSE YOU NOTICE THAT THE EYES ON THE BODY ARE BLINKING. NOW ANSWER ME THIS QUESTION:

HOW DOES A DEAD MAN MANAGE TO ACTUALLY BLINK HIS EYES? WHEN WATCHING THE EPISODE BE VERY ATTENTIVE

CAUSE THIS ONE IS VERY SUBTLE.
