I’d never heard of ASMR before 2018, but I have several friends who swear they experience it and that watching certain videos helps them deal with their intense insomnia. One such friend went out of town with me, and late at night in our hotel room, she turned on a video of a woman whispering and watched it until she drifted off to sleep. This seemed not all that strange to me, almost like listening to a guided meditation.
But ASMR is much more than a desire to listen to someone whispering.
