I could never get ASMR. Like I understand it but it never triggers. Whispers, plastic crimples, etc. It finally happened to me. Completely by accident.
Backyard metal melting in forges.
The flame of a forge got me the goosepimples good.
I went down the rabbit hole looking at people making their own hydro powered electric generators (from junkyard washing machine parts and some 3D printed parts) to people breaking down stuff and ended up at melting metal...
ASMR just kinda means "pleasant tingling", and videos with asmr in the title tend to just be "neutral stimuli that I hope will make you tingle pleasantly." Mostly they're indistinguishable from "oddly satisfying" videos with the addition of, like, sensual whispers, or something?
I wouldn't be too surprised either way if metal melting in a forge wound up in either collection of asmr or oddly satisfying.
