That's an interesting take on NW. I tend to go with "he really did go into the past" because this is Discworld and he had to deal with the differences. Also, Carcer was there, making changes, and the Monks of Time were fixing things.
I got "flash sideways" from Monstrous Regiment, where one character was getting flashes of an alternate universe war with some emotional connections. Although others heard what they said, nobody else had the flashes and they didn't actually go there except mentally.
