My idea is that there are many people gathered for an inside wedding. Due to an earthquake many objects start falling as well as part of the ceiling and in the end the only one left alive and the is the brides best friend who is crushed by this huge chandelier (I got the chandelier part from Ali Larter's Obsessed). But after the vision the best friend creates a stir causing many people to get outside causing the chandeleir to hit the bride instead.
