I think it will be definitely possible, but I don't see happening in this timeline. If you look what is happening with artifficial intelligence and wireless technology, it is a not far fetched idea at all. Few years ago I read that there is some kind of worm in forces which can actually make ordinary man acts as  zombie. So yeah, there are natural biological systems that can do this, as well it can be mimicked with engineering.

Many different ways.

@DataPoint yeah zombies most likely will not happen in this earth timeline. you gotta be put in the ssp to even have the chance of seeing a zombie of any kind. i will even add that there is the black eye club i think its called. a worm from a reptilian comes out and goes into the humans eye. then the human gets controlled somehow. i think the species is vril. i will say that i learned about it when alex jones had odd black left eye. then i noticed it happens to all kinds of people in power but I'm not gonna mention any more names. anyway i still hope the veronica virus or related never happens. i kind of feel it would happen with a controlling virus if anything. even if the accident is contained.

That's pretty nasty. I heard about that, however I heard that they get black eye because during the process of initiation they get punched, thus getting black eye stuff.

Regarding the worm stuff, what you mentioned reminds me of a video game called Dark Seed. The guy has nightmares. An inside dream he gets implanted between his eyes. The art for game did H.R. Giger. Pretty amazing but satanic stuff. I will try to find screenshots and post it here. If that stuff in the game is real, then were in a trouble. I would need once again to restructure my reality system in which we live.

Here are the screenshots:

On first image is the mechanical system for inserting the implant, which is possible with new technology but through nasal cavity and ears.

The second one is kinda like some alien(maybe Reptillian?)

And the third one is interesting because it has the all seeing eye inside the pyramid, which is there all the time throughout the game. Also maybe it could be the reference with the skull about human experimentation happening all over the world to aware and unwitting subjects.

The game also has a sequel.

@DataPoint interesting. well a lot of people in the community already have implants of all kinds. mr stormm seems to be the guy about implants around here. i should have at least one since I'm on the high functioning autistic spectrum. what seems confusing is some implants may be multidimensional so doctors here cant even find it. there is creepy stuff that they can do with implants. not sure what the theme of the game is or the purpose of the implants are so i cant say anything about a possible future. there is timelines where they might be able to hack minds. which might be more possible with implants. also paying for stuff with your face isn't a nice thought. there is actually a game called observer where the government can do some kind of interrogation. however i never played it. being punched in the same spot might leave a eye black like that but there is still stories about worms from reptilians which i think is called the vril version.

I know there were a video on youtube when man came to doctor that had pains in his hands, and they initially haven't find him anything when looking on CT scan, however upon the close physical analysis , they took out needle type implant. It was coated in special material, so it would not be detected.
