head to the Special Features menu and highlight the weird symbol in the middle by going to 'On Set Peeks' and pressing left on your remote. Press enter for a 'Haunts' menu with two options: Home Movies and Scare Reel.

The Home Movies are the full versions of those shown in the main movie and the Scare Reel is a collection of all the scary moments from the entire movie (surprisingly totalling less than two minutes).
