Watch it below:

This fourth sequel connects to Paranormal Activity 2, with Katie and Hunter, who both escaped at the end of that second film. Also, it is revealed in the trailer that they moved in next door to a family who have noticed weird phenomenon happiness in their house since Katie and Hunter were there. Hmmm, interesting. Though now I kind of have the shivers...
