ASMR

Autonomous sensory meridian response (ASMR, sometimes auto sensory meridian response)^[2][3][4] is a tingling sensation. It often starts on the scalp, and moves down the back of the neck and upper spine. It is an unusual feeling which has no obvious physical cause. (paresthesia)^[5] It has been compared with auditory-tactile synesthesia.^[6][7]

People who experience ASMR have a "low-grade euphoria". which means they like it. It has "a combination of positive feelings and a distinct static-like tingling sensation on the skin". ASMR is often set off by some auditory or visual stimuli.^[1][8] There are videos which try to stimulate ASMR: over 13 million are on YouTube.^[9]
