if you like that sort of thing there was a film made about it, it was a bit of a freddy cruger rip off with some guy with glass attached to his fingers running around killing people.
if you look in the "ring" film there are several points when the camera fades to darkness and you see the ring symbol as it goes back to the film we studied subliminal messaging in my film studies class and some does work but nothing very important can just things like making you think your thirsty/hungry.
If I could I would shrink myself,
sink through your skin to your blood cells,
remove whatever makes you hurt,
but I am to weak to be your cure.
