I appreciate your post.TEMPEST keeps other people from reading your monitor using radio waves emitted by the monitor/cables/computer.
there is no technology that can "read your mind". there have been experiments with controlling hardware by "thinking", but such systems require extensive "training" by the user, and often the equipment must read a variety of sensors (eye movement, muscle reflexes, as well as specific EEG electrodes) to get a useful response.
similarly, there are no "mind control" techniques that use electromagnetic influence on the brain. there are however, mind control techniques that use propaganda and pseudo science to separate people's money from their wallets.... more specifically by convincing somebody that they require expensive hardware to isolate the user from "harmful" electromagnetic waves. with or without technology, everybody is constantly exposed to electromagnetic waves covering the whole spectrum quite literally from DC to Daylight, all from natural sources. the sun is a huge emitter of radio waves, the earth's atmosphere is constantly generating radio waves from 8hz to thousands of Ghz. there's EM radiation that everyone is exposed to that covers everything from far IR, to light, UV radiation, X-rays, Gamma Rays, cosmic rays.
if you stick around this board long enough, you will find the intent of people here is not to hassle you, but try to inform you that pseudo science is no science at all, and you're better off keeping your money in your wallet so you can better use it on useful things...
there's nothing like pseudo science to raise our ire on this board, EMF-phobia, Flat Earth nonsense, and Over-Unity/Perpetual Motion machines are the three most common subjects that will rain fire down on the thread.
I have my own reasons for believing that mind reading and mind control exists. Because I think I personally experienced them. There is no possible way that someone or something could have known something I have thought or felt. One can infer and deduce things from writings and Internet activity, but there are limitations to it, I saw references to things in a short span of time after I thought about them, when I wouldn't even have given indications to it through my activity on digital devices.
For this reason, I'm left with no choice but to think they were able to read my mind, or control it to think along certain lines and let me see some reference to it.
I thought a lot about how this could be done, ultrasonic frequencies, but I don't have auditory hallucinations. Subliminals through monitor, which is a possibility but that doesn't explain to me how they could make references to what I thought when I wasn't near any digital devices. As I started researching about it, I was seeing these results about electromagnetic things and it seemed to explain the same phenomena which I was experiencing so I thought it would be the cause. As a lay person my understanding of these things are close to null, your explanation that EMF permeates everything is similar to saying water isn't dangerous or it cannot be used to cut as it is everywhere, but if you have been to the dentist, they have instruments, which uses water to clean teeth, the force with which it is ejected, almost feels like it can cut. Is it not possible to use EMF purposefully to read mind or control it?

Shows micorwave auditory effect, some other report over the same thing says they can make phrases and words understood by a person without making that person hear it.
