During the last 20 years, I have seen plenty of things that look like I or someone else is being "targeted" in this way, but I don't think they have any device to read people's thoughts, let alone insert thoughts to someone's head.
Instead, it looks like they first try to make sure they see and hear as much of your doings as possible, 24/7, by hacking to your computer and cell phone to see your internet browsing and to listen to phone calls (possibly asking the Russians or the Chinese to do this for them so that local authorities can't be accused for anything illegal). There are also
microwave and
terahertz radar devices that can to some extent see through walls and the way how you are moving in your home can be followed, but for this to be effective they first have to fool you to move to an apartment or house where the wall material is especially easy to see through with that kind of radar.
After they have followed you for enough time to be able to deduce what you're up to by simply looking at your behavior, they try to make you an environment that contains lots of things that are named in such a way that the names contain hidden manipulative details if you read them in an abnormal way by splitting words to pieces. A familiar example of something like this is how the serial killer Ed Gein's name creepily becomes "Edge In!" when you read it like that. it was probably this scary hidden detail in that guy's name that made his neighbors deny any clues of abnormal behavior they saw, and that's why he was able to continue his sick shit for years before getting caught. It's like you get an "edge" over other people simply by having that kind of name. People don't read stuff with that kind of splitting unless they're expecting something to contain that type of hidden message or if they're reading or listening to something they consider "inferior" to themself, and when they don't see this they can be manipulated with this type of messages without them even noticing that someone's practically giving them orders that way. The ancient Romans had this saying
divide et impera, which described how they isolated their provinces from each other to gain better control of the nation, but it also seems to say something about this human tendency to "split" things they see as lower-status (even by reading names like that), as a symbol of power.
Now, if they can easily manipulate the targeted individual with that type of hidden messages, they leave them alone. But when they find someone they call a "certified asshole", who considers almost everything as inferior to themself and isn't easy at all to fool this way, they start throwing all kinds of ambiguous insults at them. For instance, if they see that the person has a toilet habit of pissing sitting down despite being male, they could throw a pink-colored miniature toilet bowl on the yard as some kind of comment. And a multitude of other unpleasant surprises. If someone is considered an especially bad troublemaker, they can even add that kind of shit to the program aired to local television or radio channels, and when it's visible in the media it goes viral in people's behavior and even the traffic on the street soon starts looking like it contains the same type of hidden mocking as in the media. The craziest part about this is that when you're put in that kind of situation, you can feel the anxiety (like being targeted with a gun) even before you actually see what's going on in the media or on the street. It looks like humans are able to sense this particular thing from so little clues that it's like a dog sensing odors from several miles distance, which is also something that seems like it shouldn't be physically possible. During the Cold War, the Soviets and the East Germany's Stasi were able to do
human experiments with this kind of harassment without having to follow any ethical principles, and that's why the former communist bloc countries are better at using this psychological weapon than the countries of the West. And all of the details known about this aren't said publicly, because then it wouldn't be as easy to scare people with this to silence them.
And in addition to this type of harassment, t
hey also have something that can be used to cause heart arrhythmias or other scary symptoms to someone in a neighboring apartment on the other side of a wall, and this is used in a nasty way to force someone out of their home and even to sleep on a park bench. I think these "weapons" are similar to whatever they used to cause the neurological symptoms to the diplomats in Cuba several years ago. I also believe that the reason why the Danish inventor and murderer
Peter Madsen built his DIY submarine was to have a hiding place from these electronic attacks and surveillance. Radio and microwave signals don't pass through sturdy metal obstacles, and not through several meters of sea water either
unless it's very low frequency radio waves (20 kilohertz or less).
Now I'm not saying that I have any actual information about this matter, and I don't expect anyone to believe a word about this unless they have experienced this themself, but this is what this phenomenon looks like to me. And if asked for a theory about why they're doing this, then I would say that they are either trying to learn better at this type of manipulation to be able to control people once the climate and energy crisis becomes bad enough to cause riots and civil unrest, or alternatively they are simply addicted to this kind of behavior after learning this type of abuse from the totalitarian nations of the East.
