Since the latest DC relaunch (DC Rebirth) I've been reading several DC titles, and I'm confused regarding some of the continuity issues. A plotline that's been running through the current books has been the idea that someone had manipulated the time stream, effectively "stealing" memories from everyone. Sense DC Rebirth, some characters have gotten these memories back. Now, I've been assuming that these "stolen memories" are those events belonging to the pre-DCNewU continuity. In other words, I've been going with the idea that this time manipulation the characters keep talking about is what kicked of the New 52 continuity (I wasn't reading the comics when that happened). But that doesn't make sense because other books are treating the DCNewU as a parallel earth that coexists with the pre-New 52 one. The New 52 Superman, for example, has been shown to be a completely different character from the pre-New 52 one. The latest issue of Nightwing makes pretty clear that the Dick Grayson who's adventures we are now following is NOT the same Dick Grayson from the pre-New 52 comics, but an alternate one. I don't know how to reconcile this with what I've been reading in Titans. I got the impression from that book that Dick Grayson, and all the other Titans, are the same characters that we knew prior to the New 52, only with years (and therefore memories) removed from their lives, which is why they originally couldn't remember many pre-New 52 events.
So where exactly did the DCNewU come from? Some books are making it pretty clear that its just an alternate universe, as opposed to it being the same universe that just got effed up by someone messing with time. But if that's the case, what is all this "time theft/stolen memories" talk about?
Can someone help me out here?
