I bought stuff from Amazon which I didn't need. Probably there was some mind manipulation there, but not mind control.

I'm curious about the same thing.

Maybe after injecting, or making us inhale, drink, .. nanorobots, they can control our mind
directly.

Maybe by saying some confusing, repetitive things in a special way (fast, slow, confident)
you can create hypnosis in other people.

Sometimes, suddenly I start hearing a special ear ringing sound, .. and I can stop/reduce it. I feel maybe I switch to another mental state when this happens. If it is mind control, then it must be a remote one.
