long story and i barely remember it
i was watching a horror(?) movie about a kid who had his grandma locked in his closet for his own safety and every night he would lie awake because his grandma kept banging on the door
one day his grandma broke out of the door and her jaw looked like it was either opened wider than normal or dislocated
she attacked the kid and the kid managed to push her off and then she transformed into this weird loving amorphous spaghetti brain monster with a giant eye on top and absorbed the kid into itself
