Alright, so I've done some research on this topic (I've had this sensation for quite some time now, being able to trigger it at will), and the sensation is called ASMR .
"ASMR is described by some of those susceptible to it as "akin to a mild electrical current...or the carbonated bubbles in a glass of champagne".[8] The tingling sensation on the skin in general, called paresthesia, is referred to by ASMR enthusiasts as "tingles" when experienced along the scalp, neck, and back.[15][16] It has been described as "a static tingling sensation originating from the back of the head, then propagating to the neck, shoulder, arm, spine, and legs, which makes people feel relaxed and alert".[5]
So all this 'superpower' that you guys have been talking about really is, is a relaxing sensation that some people just naturally have, and others really want (just look at the insane mass of people watching all the 'ASMR' videos on youtube).
Yeah, nothing too extraordinary.
