As a little boy, I was very curious of my five senses. I wonder if it was possible to make my ears stop hearing sounds, without blocking my ears externally. I told myself if I did not want to see, I close my eyes. Therefore if I do not want to hear, I must close my ears. I know in order for I to hear, incoming sound vibrations vibrate my air drums, which then travels along the auditory nerves to the brain. This is then interpreted by the brain. I said the reverse has to be possible. I then carried out an experiment. At will, I used my brain via thought to vibrate my ear drum, thus my ear became an emitter of vibrations instead of receiver of vibrations. At this point I ceased to hear external sounds, thus I stopped hearing without blocking my ears externally such as using my hands.
I experimented a lot with this newly found ability. One day I was walking in a strange neighborhood, as I passed in front of an open driveway, a ferocious dog barking furiously rushed at me. It was going to bite me. My adrenalin hyped and I started to vibrate at will thinking, "I am a friend, I am friend." Immediately the dog became calm. It turned tail and walked away quietly out of sight. Thanks to my latent talent.
