Right around the time the official trailer for ‘Paranormal Activity 4’ hit the web, a new shorter one was released asking “What Really Happened?”

The trailer is part of the ‘Want It’ Facebook promotion where fans can vote for their city to get an advanced screening of the film. The Top 25 cities with the most votes will have the opportunity to find out what really happened to Kristi, Katie and Hunter.

As usual, the details of ‘Paranormal Activity 4’ are being kept under wraps but from the looks of the trailer, it involves a teenage neighbor and seems to pick up where ‘Paranormal Activity 2’ left off.

Directors Henry Joost and Ariel Schulman have returned to helm the fourth installment of the franchise based on a script written by Zack Estrin (‘The River,’ ‘No Ordinary Family’).

‘Paranormal Activity 4’ will begin scaring movie goers on October 19th.
