The movie, knowing with nicholas cage.. scarry?

i AM petrified of scary movies. i am petrified of ghosts and all those other unreal things.. i could not sit through the ring or the grudge, in fact the grudge is the last thing i have seen. I REFUSe to watch scary movies.. will knowing bother me? how scary was it? was it scary for reasons that its the end of the world or do supernatural things occur that i would be afraid of?
