ive been able to creat a buzzing/tingling/numbing sensation throughout my body and recently gotten better at it...

sex:male age:19 wieght:210 height: 5'10" race: caucasian location: florida (though ive traveled as i was a military brat) duration:all my life medicla issues: N/A unless you count EEE (though not relevant imo) medications: N/A NO THIS IS NOT A JOKE NOR A NOSLEEP STORY....okay. so ive probably always been able to do it, but ive realised what i was doing wasnt really normal not 6 months ago when i sat down with my brother and dad and just wildly asked about it and they looked as if i was mentally ill to put it nicely. I had to explain it to them and realised it was very odd. neither of them could do it and from what i knwo not many others can do what i can, if not alone in my mutant freakishness. So ill start with what it is. I believe it acts as a muscle. I'm able to turn it on and off just like sending messages to a muscle. Im able to "flex" it as in i can increase the strength of this sensation. Also ive learned to get better at controlling it and can now localize it to any limb (no more than one area). When i say that it is a buzzing or tingling sensation, i dont mean that it makes any sound. its completley internal. also id like to add that when i bring the "power" up to its max, some muscles such as my forearm feet calves or hands will twitch just a little. Also if i keep the power up too high for about 15 seconds max i will feel too overwhelmed and be forced to stop. this isnt to say its painful or uncomfortable its just so...disconnecting and the tingling becomes almost ticklish? that i cant focus on keeping it up. Now for a wierd part...Ive found that it can act as if it is an anesthetic or at least a numbing agent. Ive put cold/hot water on the chosen areas and i do not feel the difference very well, my brother has pulled hairs form my legs (dont judge us we were testing its limits) and i felt no pain other than pressure, and ive stupidly tried the old putting salt on your arm then sitting an ice cube on top of it. i kept it there for nearly 3 mintes and felt nothing of the onsetting frostbite or any pain. just...pressure of sorts... Ive researched this because its recently begun gnawing at my insanity. i want an answer now that i reliase i can get better with this and i want to know everyhting about it.PLease do not suggest ASMR. i know it is not any form of this becaue i am the one triggering the sensation. theres no external triggers to catalyze the feeling. I am the only thing that controls it. Ive recently looked into the vagus nerve, being the wanderinng nerve ive thrown around the possibility of it being the ability to tap into it and im able to feel its paths. Now im no man of pure science. i have some faith. but if you tell me im some sort of reincarnation of a buddhist monk able to tap into pure meditation or i am able to master a technique of tai chi, you would have to REALLy prove to me that this is the case. This includes my chakras, the ability to absorb energy of life sources around me, or being enlightened to becoming the next level of humanity. honestly id jbe fine with a point in the right direction... EDIT: added some more information
