In my story, some aliens try to conquer humans by slowly copying their mind into humans heads. This copy process is called “enlightenment” by the ones who undergo the transformation. For example, by using subliminal stimuli based technology like 25th frame. It is worth noting, that there are few Aliens — about 1 alien to 5000 Humans. And the enlightenment process actually rebirths the alien's mind into the human's body: the human's mind is merged and absorbed into the alien's, and the alien's body is destroyed (so the mind cannot leave the human's body). The process is quite slow: a few months/years.
A person being enlightened slowly forgets usual humans desires (“I don't need sex/money/rock'n'roll any more”). They hear voices (“Angels told me to do this”). At the same time they develop unusual skills (telepathy, telekinesis) and wills (for example, urge to “enlighten” the non-enlightened, build strange devices, eat maggots), while regaining all their human memories. So, with some basic training it is trivial to find the enlightened among other people.
I have these questions:
How can modern humanity can fight this?
- Quarantine the enlightened?
- Develop drugs against the technology?
- Hunt for strange ones?
- Keep everything secret?
How can the memory implantation be performed stealthily, without physical contact and abducting people?
