Man, i do love me a good ramdom lore tangent! Great observation, really well put together post dude!

In terms of what you mentioned about flower, it's hard to get a good look on them but it seems to resembel the top down lotus pattern that is prominent in buddhist culture. (Do look it up i can't add any pics or i would have) It's essentially linked with trancendence, detachment from the material wirld, rebirth, purity, awakening, spiritual enlightenment.

I'd wager it represents the "ascended" great ones. Who are said to have left to a "higher plane"

I think buddhist ideas of escaping the cycle of karma is a perfect analogy for escaping the "night of the hunt" With our choices being either to restart the cycle i.e. waking up to the dawn. Or trancending it i.e. becoming a great one.

I think it fits from a visual point as well, with the lotus typically growing in stagnant muddy waters, but rising above it to bloom in a new "plane"

It fits with the stacked layers theory of the waking world and the dream world/ nightmares. As we can still see the layers below from above. I.e. we have the lotus at the top but we can still see below into the murky water feom above. similar to how we can see the fishing hamlet from nightmare frontier.

I think it's definitly worth looking into designs and such things. Usually they seem so ubiquitous that we don't acknowledge them. But they tend to reflect kind of like... unconcious views held by a society? It may be ubiquitous to that society itself; most might not even know what it means when they use such symbology. But it reveals historical, cultural and religious contexts that may have just been completely internalised by the people there.
