Not surprising at all.
We know that a lot of "fine skin sensitivity" goes totally out the window under "life'n'death struggle" circumstances (regardless of whether it's a "combat situation" or not). I know I was able to cling to a rock on a rocky coastline while being hit with a mini-tidal-wave that would have otherwise killed me at age 12, and got full use out of a previously sprained wrist. Totally shrugged off the pain. My brain did all kinds of other "special effects" like shutting down hearing, and the whole world seemed to slow and I had all kinds of time to plot out strategy despite being about 8 seconds away from doom. I've been in that same "mental place" about half a dozen times since and while I didn't experience anything that would have otherwise caused me pain, I have no doubts whatsoever that my pain threshhold in such an "overdrive" condition is high bordering on non-existent.
(Which is why when you start reading about shooting incidents and what went right or wrong, you start hearing about people grotesquely wounded yet they keep fighting.)
While anger alone doesn't trigger an "overdrive state", it's a prelude to "berzerker rage" which is something else entirely and that's even more of a mental shift (to be avoided at ALL costs, in my opinion!).
So your brain *definately* controls skin sensitivity based on needs, and almost certainly by moods. Which suggests the opposite too: if you genuinely like being tickled, and *want* it, and know it's coming as you lay there tied and helpless, sensitivity goes through the roof
😛.
(Sidenote: "Berzerker rage" and "overdrive" are similar in some ways, but different in others. Overdrive does not rob one of the ability to make moral choices - one can still "moderate their force" in a fight to only the degree necessary to solve the problem. I know that for a *fact*, personally. Overdrive is emotionally flat, highly calculating, extremely rational and reaction times are off-scale fast. A berzerker is anything but rational - I hit that state once many many years ago as a kid, swore off of that forever. I also had a chance to speak with an actual Berzerker in the original sense: a soldier deliberately programmed to go absolutely psycho on a battlefield. Iran's Mullahs had done it to him, at age 14, and armed him with an Uzi as part of a human wave attack on Iraq.
