I thought I'd look up some basic stuff about ASMR since I sorta knew what it was about but nothing past that. I thought it was something old coming back as a fad, but the name and documentation is actually pretty new.

the usual audio triggers work for me, most stuff besides mouth sounds which I just find offputting.

I wonder if (at least in my case) it has something to do with latency in sensations. hard to explain, but I think of it like the ringing after a peak through a filter.
