I think this is memories of a past life, possibly the first celestial/ chosen one pair. And, as we've seen, those with red hair and green eyes are those with imperial blood. Also, celestials tend to favor those with imperial blood. My theory is that the reason the celestials favor those of the imperial bloodline is not because of the nobility, but because of the first pair. Between Snow and LanRan, maybe they are the reincarnation of those originals, and that's why the instant connection from birth/ creation? Idk, I feel like it must be both of them in the past, because I'm unreasonable and don't want this to mess with my otp lol. Otherwise, at the very least this is Snow's past life, since this celestial also had silver hair.
I hope Snow remembers this dream properly and ponders over it it will help him better understand what he's feeling for ZaiWin so he won't be so confused when those feelings come up and he can understand the differences between those feelings and it will help if ZaiWin speaks to him about what happen and gives him a proper explanation like how the red head did, speaking of which red hair green eyes royal family huh maybe the first royals and this could be Snow's reincarnation. Thanks for the chapter
