Autonomous Sensory Meridian Response (ASMR) is a neologism for a perceptual phenomenon characterized as a distinct, pleasurable tingling sensation in the head, scalp, back, or peripheral regions of the body in response to visual, auditory, olfactory, and/or cognitive stimuli.
There's a name for it!!! ASMR - Autonomous Sensory Meridian Response. That blissed out, super-relaxed feeling that literally makes your scalp tingle! One of my triggers is the sound of certain vacuum cleaners. When I worked evenings in an office, the cleaning crew would come in and switch on a vacuum. I could barely keep my eyes open!
