It really is just another word for kindness and respect at the end of the day.
That sounds like it could absolutely be a kin adjacent alterhuman thing. Some ideas that come to mind you could look into:
Hearthome (heart home): an experience like a hearttype but instead of being connected to a person/character, you’re connected to a place or world.
Parallel lives: a fictionkin and otherkin experience where instead of your kintype being the result of a past life, it is the result of experiencing your own current existence simultaneous to this one but in another world.
General past life experience: it could be nostalgia for a prior existence, as Egon Spengler famously said “past life experience intruding on present time”.
We’re pretty certain that we know the user that you’re talking about, and we had the same reaction.
It’s a shame.
Well, that’s certainly a kind of whiplash, isn’t it? We’’re glad you got your blog back.

Welp I drew a bunch of other stuff for a thing earlier so I guess now it’s back to business as usual, because this is clearly all I do in my free time.
oof.
