                                            Amy's babysitter gets locked inside a closet and the lights go out, causing her to knock furiously on the door until her hands are bloody - only to discover later there's no lock on the door. |

                                            One night, Kathy wakes up looking decades older than she really is. It takes hours for her appearance to return to normal. | 
                                            In the climax of the film, Kathy briefly appears very old, but it's completely out of context and she looks normal again in the next shot.

                                            At night, Kathy is attacked by an invisible force in bed, leaving red welts on her body, and levitates in midair. |

                                            This was invented for the movie. Father Mancuso never went blind. | 
                                            Father Delaney holds a mass for the Lutzes praying for their protection, during which he suddenly goes blind.
