Scary Movie Search

I want to say it's a horror movie, maybe by Stephen King.  

I little girl in a hospital (mental???) is being haunted to chased by ghost or demons and this old black man saves he by yelling at her (or more of at the spirits) "Come to me! Come to me!!" and in the middle of saying this he seems to freeze and fall down?  

Can't think of any other part of the movie than that.  Can y'all help with the title search?
