I also happen to be able to trigger asmr at will pretty much instinctively; the intensity sometimes is weak though if i cant concentrate due to interference. The intensity is far greater than when it is caused by external stimuli though. Anyone alse capable of directing the feeling (always starts at the base of the skull for me) to parts of their body at will??
So how do you know if you have ASMR? There’s no single way to tell for sure, but for starters, you can watch some of the internet’s most popular videos and determine whether they elicit a tingling response. And for your convenience, we’ve compiled some of the best ASMR videos that YouTube has to offer—so get those goose bumps ready, and while you’re at it, try these brain teasers to find out whether you’re smarter than an astronaut.
Finally something to explain my “photocopier man” feeling which has been a standard joke in our family. I first discovered this feeling when I was a teenager working in an office where a repair man would come regularly to maintain the photocopier and I would experience this sensation of well-being while he was working. It was in a fairly small office and usually he would clean the screen with an acetone base cleaner so I always thought that the fumes from that created a mini “high”. I have had it at various times usually when there is someone repairing something in the office eg putting data cables, fixing sockets etc. I now work in a research lab and have had it when participants are in another room being tested with senors on their heads and I have no visual or auditory input from them just the sense of them being there. I have had it to a lesser extent from acupuncture and find massage of any kind extremely unpleasant. It’s nice to find out that it’s not just me that has this strange feeling for no apparent reason.

YouTube stat tracking service SocialBlade estimates that the "Life With MaK" channel can bring in about $1,000 in advertising revenue, or more, in a single day. That puts her on a par with ASMR Darling, also known as Taylor Darling, the biggest name in the ASMR space with 2.2 million subscribers. ASMR Darling now brings in about $1,000 a day, Wired reported, which roughly jibes with SocialBlade figures.

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.
I forgot to mention and may be interesting to people curious about such effects. One "mantra" or intention that I have assimilated in silence and often keep repeating softly inside is "Bless All Beings". There's a famous Sanskrit mantra that basically says the same, but English also works, and may work better for Westerners as intentions need to have meaning, not just repeating syllabuses without understanding or intention.

Satisfying Slime ASMR: With close to 1.5 million subscribers, this is the go-to channel for crunchy slime videos. They post multiple videos a day, all related to slime, games, and toys. Their videos fit into several series related to food slimes, DIY (do it yourself) slimes, cutting stress balls open, and ASMR-specific slimes. Their most popular video about rainbow slime has over 45 million views!
Replies to this post indicated that a significant number of other people had experienced the sensation which "okaywhatever" described - also in response to witnessing mundane events. The interchanges precipitated the formation of a number of web-based locations intended to facilitate further discussion and analysis of the phenomenon for which there were plentiful anecdotal accounts,[12][24] yet no consensus-agreed name nor any scientific data or explanation.[17]
The study is still ongoing, and results have not yet been published. But for his part, Richard has been developing a theory of what ASMR is and why it exists. His theory isn't exactly scientific, but it is beautiful: He notes that the quality that underlies almost all ASMR videos is what’s been called a “tranquil, womb-like intimacy.” That is, ASMRtists speak softly into the ears of headphone-wearing viewers, gently coaxing them to sleep by way of assiduous personal attention, comforting words, smiles and simulated stroking. At its most essential level, Richard believes, all the intimacy channeled through towel foldings and whispered affection is about triggering the felt experience of being loved.    
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.[15]
