Daniel and Prunkl keep a folder full of this man’s transgressions and have notified the local police. “Sometimes it scares me,” Daniel confesses, quieter now. “It does scare me that this guy could be anywhere.” Similarly, Makenna Kelly fears that kids at her bus stop will follow her home and leak her address online. “I just go down to the clubhouse and wait ten minutes just to make sure nobody knows where I live.”

The French word 'frisson' signifies a brief sensation usually reported as pleasurable and often expressed as an overwhelming emotional response to stimuli, such as a piece of music. Frisson often occurs simultaneously with piloerection, colloquially known as 'goosebumps', by which tiny muscles called arrector pili contract, causing body hair, particularly that on the limbs and back of the neck, to erect or 'stand on end'.[54][55][56][57]
The most popular source of stimuli reported by subjects to be effective in triggering ASMR is video. Videos reported being effective in triggering ASMR fall into two categories, identified and named by the community as 'Intentional' and 'Unintentional'. Intentional media is created by those known within the community as 'ASMRtists' with the purpose of triggering ASMR in viewers and listeners. Unintentional media is that made for other purposes, often before attention was drawn to the phenomenon in 2007, but which some subjects discover to be effective in triggering ASMR. One early unintentional example is the Art Bears song 'The Bath of Stars.' Another example of unintentional media several journalists have noted is of famed painter Bob Ross. In episodes of his popular television series The Joy of Painting both broadcast and on YouTube, his soft, gentle speaking mannerisms and the sound of him painting and his tools trigger the effect on many of his viewers.[30][31] The work of stop-motion filmmaker PES is also often noted.[32]
Four months after Novella's blog post, Tom Stafford, a lecturer in psychology and cognitive sciences at the University of Sheffield, was reported to have said that ASMR "might well be a real thing, but it's inherently difficult to research...something like this that you can't see or feel" and "doesn't happen for everyone". Stafford compared the current status of ASMR with development of attitudes toward synesthesia, which he said "for years...was a myth, then in the 1990s people came up with a reliable way of measuring it".[41]
So. I found out about this roughly… an hour ago. And holy… what an hour it’s been. I didn’t even know I could feel this type of stuff (although for most it seems to be in their head/scalp/neck etc, for me, it’s in my chest.). My biggest trigger seem to be taps… from the crisp tap to a low thump. One thing I am noticing though, is how many girls do the videos (I can understand this, as a female voice generally has a more relaxing effect.) but I was wondering how many people prefer a male voice? Any preference to accents, etc.
In addition to the effectiveness of specific auditory stimuli, many subjects report that ASMR is triggered by the receipt of tender personal attention, often comprising combined physical touch and vocal expression, such as when having their hair cut, nails painted, ears cleaned, or back massaged, whilst the service provider speaks quietly to the recipient. Furthermore, many of those who have experienced ASMR during these and other comparable encounters with a service provider report that watching an "ASMRtist" simulate the provision of such personal attention, acting directly to the camera as if the viewer were the recipient of a simulated service, is sufficient to trigger it.[5][16]
