Just prior to meeting with the Nightwatcher 5.5 years ago, Dalinar wakes up at the end of a highstorm and seems to have experienced a vision from Stormfather. But in The Way of Kings, Dalinar says that the visions only began "a few months ago." He also seems to have specific memory of the "first" even if he can't recall all of the details, and it seems unlikely he would have visions for several years without anyone having noticed.
So, should we assume that (1) this strange "dream" in Oathbringer was not actually a one of Honor's visions? Is that just a weird dream, or perhaps some OTHER vision from Stormfather?
Or, (2) this is one of Honor's visions and any contradictory details from The Way of Kings are superseded by Oathbringer?
Or, (3) this is one of Honor's visions, and Dalinar just doesn't remember his history of the visions very well.
So, I did this quite intentionally, it's not number two. But I expected these questions to be asked, and it's a RAFO, but it's one of these RAFOs where I wrote it very deliberately the way I did on purpose, and I'm going to leave it to your speculation as to what it means.
