in the movies the house itself is stated to be behind driving people insane and is the reason demons flock to it - the whole "get out" voice etc is the house itself.. most of it is purely for film, it never occured in the haunting in reality (most of the real life haunting was actually a hoax mixed with psuedo-paranormal investigation, claims of "demons" and "Indian burial grounds" making it highly unlikely to of been real).

the movies made the house itself malevolent, much like the titular "House" from another horror franchise.
