But you can still hear the caller through vibrations.

So if your phone can do this, what if a modulating signal down your powerline through powerline technology will cause your kettle, or fridge to vibrate and hence alter your thinking process through a modulating subliminal. I think this can also happen through a strong enough radio frequency which can penetrate your tissue and cause it to vibrate and hence pass the vibration to your ear drum or your cochlear to create an impression or even a voice in your mind. http://www.tomsguide.com/us/usb-tv-tuner-software-defined-radio-sdr-radio-spying-privacy,review-1836.html
A frequency counter will tell what is the dominant rf frequency in your space. With a decent aerial it is a very inexpensive way of visualising the unseen space around you.
Also, as noted in the link above, household electrical items can be identified with software radio where some of the frequencies can penetrate walls.
This is the signal from a 433Mhz remote control. It will pass a few walls to get to its intended target. You can see the signal pop up on the screen, as below, when the “missile” is deployed. A modified signal strong enough after amplification can make your head to sing a tone, penetrate your skin, cause it to vibrate, and pass on a subliminal message. This signal is only present when the remote control is used.
So I thought it will be good to have a birds eye view of signals present;
I got the 392 Mhz frequency info on the pic above from ofcom. I am not too sure about the loudness rating on that signal but safe to say it is a “loud” signal? I would assume that the tinnitus level in the ears would be ringing with that signal and if it is modulated with a subliminal message the brain is going to find its meaning for you!

The mind is under attack in the new world and invisible missile subs are deployed everyday in the city due to the modern living environment.
A 433 Mhz signal will have a tissue penetration of 3.57 cm.
So are your thoughts really your own when you are at home.
Vibrations can generate subliminals and alter thinking.
The future is here today.
