In Westworld episode 1.05 (Contrapasso) viewers begin to see how Arnold's reveries work to slingshot consciousness, as Dolores continues to "remember" the past.
But in some sequences, it appears that in the past, Dolores is also "remembering" the future and not the other way around! She has several conversations with young William (or Billy) that show the audience that she is "lost in her thoughts and/or time" (definition of what a reverie can be), but also seems to be able to recognize concepts of the "real world" when William speaks about it, in which she should not be able to do. In each era Dolores is in, feels like she exists in time slips.
However, in another scene set in the past Dolores sees herself walking in a crowd and begins to follow herself (a reverie in a reverie?).
So my question is, what exactly is going on here? Are Dolores' memories semi-faulty with the code creating some improve to the memories she has access to or was she in fact remembering the future, suggesting something else (predetermined universe or some kind of time travel) is at play here?
