Weird videos put some people in mind&body?

mashable.com/2015/01/26/asmr-youtube/ is an article about people that have an interesting response to a video of someone stroking a microphone with a brush. My first guess is just that the subjects are entering 'mind and body', then absorbing on the sensations created in their nervous system caused by the sounds from the video.

I think it's cool because it's a left-field entry to meditation for people that never would have had the experience.
