Every Empath is different but I have not seen a common theme between all the ones I know. I myself have a really weird experience with this (as Empaths normally do with everything). I listen to ASMR every night for about 6 months with no reactions until one random day. Now I get it very occasionally with no pattern in sight. I do know Empaths who get it with basically every video they watch and some who just find the sounds of asmr creepy and do not get the tingle at all.
Sounds like just normal. When you feel it you know it. That jumping around sensation can start just like yours did. Mine starts at the base of my neck traveling up like the hairs on the back of my neck are standing up, but more relaxing and very nice. Feel like giggling inside, then shoots up to my scalp and down my arms and waves travel everywhere. Whole thing can be over in a few seconds. Experiencing the trigger over again still produces symptoms but maybe not so much/or in different places. You get to feel kind of drugged. I may not feel it if I listen to a song I love from beginning to end, but will if it’s a snippet of the chorus or lead up to it. A few minutes ago I got triggered from hearing a sample from iTunes of a song I bought recently. That song has a lot of trigger types in it. Sounds like whispers or gentle waves, light tapping beats, breathy singing, violins.
Smith speculates that ASMR may be similar to synesthesia, the fascinating neurological condition in which people see numbers in color and “taste” shapes. “In synesthesia,” he says, “there have been some studies that show there’s slightly atypical wiring in the brain that leads to slightly different sensory associations, and I think that may be the same thing we have here.”
OMG I thought I was alone this whole time (and I am almost 30 years old). I thought I was strange and I thought I just was (and I hate to use this word but I don’t know another one to choose at this moment), attracted to these sounds.. even the Bob Ross one. I have loved the way certain sounds resonate with me ever since I was a very small child. I have purposefully bought movies and kept recorded TV shows on my DVR just so I can replay certain parts with the sounds and people’s voices that have triggered for me. I feel so relieved and happy to know there is a whole community of people just like me. This is actually the first time I have ever told a single person about my feelings on this. I have kept it hidden for years thinking someone would find me strange. I can’t even begin to describe the relief I feel knowing other people experience these triggers and feelings. I am excited to explore this further.
