i don’t know if this is too late to post this here, but I can do this thing that I start in my ears- it kind of sounds like thunder.. and it kind of travels down into the area between my shoulder blades.. sometimes i can do it so intensely that I can shudder. This only becomes an involuntary action when I’m sick. I never thought anything of it before, and past google attempts at “making thunder sounds in your ears” and other silly variations turned fruitless. I don’t know if this is the same thing you guys are talking about it, but if anyone wants to talk to me about it- I’m all ears!
Many of those who experience ASMR report that some specific non-vocal ambient noises are also effective triggers of ASMR, including those like the sound of rain, fingers scratching or tapping a surface, the crushing of eggshells, the crinkling and crumpling of a flexible material such as paper, or writing. Many YouTube videos that are intended to trigger ASMR responses capture a single person performing these actions and the sounds that result.
