This sound is from ASMR Soundboard

ASMR is a tingling sensation that usually begins on the scalp and moves down the back of the neck and upper spine. It is most commonly triggered by specific auditory or visual stimuli, and less commonly by intentional attention control. It has been compared with auditory-tactile synesthesia and may overlap with frisson.
