some victims have been implanted during a dental procedure

they can i believe induce a target to fall into a deep enough sleep, while sleeping at night, that they can enter the targets house and bedroom, administer surgical anaesthetics, and implant the target. that is basically what was done to me. i was also given a post hypnotic suggestion to discourage me from talking about it but that kind of think isn't always successful, some do recover memories and that is what i've done.

probably some people who think they've been "abducted" have been implanted

the information is disappearing from the internet, but you can probably do some google searches and turn up information about people who have x-ray scans showing they've been implanted, and people who have had such implanted devices removed
