I think we all agree that Dolores' perception is screwed up, and that she does sporadically "flash back" to prior events (i.e. The Church). But these flashbacks are just that - flashes. She's only able to access past memories very briefly and in fragments, and when she does it leaves her visibly shaken and confused. She wouldn't be able to remember a sustained sequence of events like her adventure with William. Hence it must be occurring in the present.
