There are three "Paranormal Activity" endings, and all are scary enough to make you sleep with the lights on for three days straight. "Paranormal Activity" is an American supernatural horror flick released in 2007, and was filmed to look like actual video footage from a couple who is experiencing supernatural occurrences in their home. The film was directed by Oren Peli, and stars Katie Featherston and Micah Sloat. Below is an overview of each of the endings of "Paranormal Activity", including the original, alternate, and theatrical endings.

  1. Theatrical ending. The ending that viewers saw in theaters when watching "Paranormal Activity" is perhaps the scariest and most shocking of them all. It shows Katie getting up in the middle of the night again to stare at a sleeping Micah, and she continues for about two hours. She then walks downstairs and we hear a scream that immediately wakes Micah, who rushes to investigate. Viewers then hear a loud struggle going on, and then a sudden period of bone-chilling silence. Footsteps can be heard just before we see Micah's body thrown at the camera and Katie standing nearby. Katie, who is covered in blood, kneels down before the camera and smiles devilishly and darts at the camera before it finally cuts to black. Text appears to say that Micah's body was discovered soon after by police, and that Katie is still missing.

  2. Alternate ending. Also quite shocking, the alternate ending of "Paranormal Activity" also begins with Katie staring at Micah as he sleeps. She eventually walks downstairs and screams, waking Micah who runs to see what is happening. A brief period of a loud struggle is heard, and then abrupt silence. Heavy footsteps are heard just before a bloody Katie enters the room, with a knife in hand. After closing the bedroom door, Katie walks up the camera and stares at it for a few moments. All of a sudden, she takes the bloody knife and slices it across her own throat and drops to the floor as the film cuts to black.

  3. Original ending. Like the previous two endings, the original ending of "Paranormal Activity" shows Katie staring at a sleeping Micah, going downstairs, and screaming. Micah rushes to the noise, and a loud struggle is heard, followed by silence. Heavy footsteps are heard before Katie, covered in blood and holding a bloody knife, walks into the room and sits on the bed. She rocks back and forth on the bed until the next day, when a friend calls and leaves a concerned message for Katie and Micah. Hours later as Katie is still on the bed, the friend is heard entering the home. We hear her discover the body of Micah, and she runs out of the home. A while later, Police enter the home to find the body of Micah. They eventually go upstairs and discover Katie, who immediately comes out of her demonic state, and is confused as she approaches the police holding the knife. The police ask her to drop the knife, but the bedroom door suddenly slams shut, and the policemen shoot Katie when startled by this. She collapses to the ground, and the policemen then discover the video camera that is still running.
