my guesses

so it seems like the translation is a little confusing, but it's not like the context of the art helps clear up much. the author seems to be creating a story more like old mythology than modern stories. old myths tend to be very, very strange, unpredictable, and sometimes more of an allegory than anything coherent. there does seem to be some coherency, though. if you know your asian mythology you can just skip the next paragraph tbh.

first, peaches in chinese (and other asian cultural) myth are a food of the gods that grants longevity & immortality, similar to ambrosia of greek myth. so they're literally divine. they're also a symbol of fertility & have been used many times as carriers for divine human-like beings. having the mythology to allude to seems pretty foundational with this story.

now, from what I can gather, MC is a magical being from a strict, small (blessed?) tribe, and the people (or maybe just the special ones?) are able to bestow their own life force as edible pearls. being that the ML runs a place called Dream, we could infer perhaps this club name is literal, but if not, it seems to be in a divine realm, and as such, things won't make sense as they do on a normal, mortal realm. it also seems that either ML is a possessed man, or a wholly supernatural being that can glamor/shapeshift into the human man we see. this is also why the mention of souls, crossing the river, and the proposal of going to a hell-like place fits in, as these are common in old mythologies across the world. as for the flying dicks, i don't really know. they're old fertility icons that were used in ancient rome, but I don't really know how they tie into this other than general fertility imagery & otherworldlyness. the rest, I have no idea wtf goin on.

anyway, people tend not to hallucinate & create highly strange tales from alcohol. if they're on something, it's not booze.
