Something wired just happened. I was playing with my knife while I was trying to fall asleep. I used it to scratch my head and I accidentally poked myself right in the middle of the forehead. Strangely it felt good so I poked the knife a little harder in that exact spot. It felt amazing, my mind stopped racing and it felt like a hug all over my body. It dosnt work anywhere but that exact spot. What did I discover?
