My story is an ongoing one. I feel like I can voluntarily influence certain frequencies of sound vibration.
Certain older televisions emit a high-pitched sound, and it is detectable, for some people, while others do not pick up on the frequency, even though it’s there. So, while these instances are not necessarily unbelievable, or would something like that qualify as "psychic", I don’t know.
In my case, I feel like when I near a television that’s emitting those sounds, I can amplify the sound. And, at that point, it then becomes detectable by others standing nearby, whereas, had I not approached, it would’ve gone unnoticed.
I did some research and found it's a transformer from line voltage down to usable electricity that vibrates to generate an audible tone. Older televisions do this and of course there are transformers on power line poles that hum as well. It is, of course, vibration at certain frequencies.
I would love to hear back from anyone who can relate to this.
