One of the most touching moments is when he sits in an ordinary living room and talks to a couple who believe their dead son appears to them on their television. Grosse himself then becomes overtaken by emotion and has to leave the room.
As you watch the film it becomes clear that Grosse believes that it is these intense feelings that give people, and the places they live in, the power to summon up poltergeists. The feelings give people something special - the power to pierce through the disappointing reality of their suburban lives and enter into something new and special. Another, and possibly better, world of high drama and raised emotion.
