How did Paranormal Activity end in your theatre?

I went and saw this movie and was totally freaked out, then my boyfriends brother saw a bootleg and said the ending he saw was totally different. That's when i started hearing that different theaters had different ending, so what was yours?

i had the chance to watch the original ending.

The following information was taken from wikipedia:

The original cut of the film, which was sent to potential distributors and has since been circulating on the internet, was somewhat different from the version currently being shown in theaters. While the original was longer, at 97 minutes, several scenes present in the theatrical version were absent, such as Katie discovering her keys on floor and Micah's picture being slashed. The original cut also included an extended scene involving footage of a possessed girl (whose story was read by Micah on the internet) chewing off her own arm.

This version's ending did not involve Micah's body being thrown at the camera, but instead featured Katie returning to the bedroom, after the struggle heard downstairs, wielding a knife with blood on her tank top. She then sits next to the bed and rocks back and forth in a catatonic state throughout the remainder of the following day. Her friend Amber calls the house, and later arrives, discovering Micah's body downstairs. When police officers arrive, Katie comes out of her catatonic state and approaches them. The officers instruct her to drop the knife, but shoot her after being startled by a door suddenly slamming behind them. The movie ends with audio of the police discovering the camera as the credits roll.

-Third version

According to director Oren Peli, a third version of the film was shown at only one public viewing. This version's ending reportedly featured Katie returning to the bedroom with the knife and slitting her own throat in view of the camera.
