Due to the impact of the 2019-20 coronavirus pandemic , the WWE match between John Cena and Bray Wyatt , presented as a self-referential series of dream sequences within Wyatt 's mind , was filmed in an empty arena .
While the majority of matches were filmed in the empty arena and presented plausibly live , two matches were presented as filmed segments with an atypical style , such as a `` Boneyard match '' between The Undertaker and AJ Styles ( held in an outdoor setting ) , and a `` Firefly Fun House match '' between `` The Fiend '' Bray Wyatt and John Cena ( which was presented as a self-referential series of dream sequences within Wyatt 's mind , spoofing Cena 's early WWE appearances and other wrestling programs ) .
