My Skull Is In Animation

My skull animates I see it talking, chewing, chuckling, Moving right and left Sometimes with horrible gape It wants eating everything; I see and I am wonder of it People around me also see it But they take it normally, They are not bothered A little bit even indirectly, They are in eternal oblivion; How will I be normal? When I see it bites my own hands, Cuts into pieces, Makes me bleeding, Sometimes I am swooned; Yet I am alive! My skull is in animation.
