Around 2 years ago I had terrible insomnia, partly related to anxiety issues. Got talking to a friend of mine and she introduced me to ASMR: Autonomous Sensory Meridian Response.
"The term "autonomous sensory meridian response" (ASMR) is a neologism for a claimed biological phenomenon, characterized as a distinct, pleasurable tingling sensation often felt in the head, scalp or peripheral regions of the body in response to various visual, auditory, olfactory, and cognitive stimuli."
I got on Youtube and found a few videos...and WHAM, I was out like a light. I told a relative who suffers from insomnia about them, and he found them helpful

I hope this can be of help to someone
