A little reference to Mark III cloning is in the movie Inception, instead of dreams think clones, they make it rather complex to get it accross but so, when people are in "Dreams" the people in the outer dream can play music to that person and the person hears it even though they are under... NOW.. In Mark III clones when you are in the outer world, people could play music to you in the Mark III clone world and you'd hear it in real. In the movie inception, they basically just reversed the roles of how you see it. I hope that makes sense. So. To Fuck with you, like with Don, these asshole can talk at you or show you fucked up stuff as a Mark III clone and if you don't actively attempt to ignore it you can end up slipping into that world and seeing it, which to certain individuals would be very maddening, and can be used as a way to fool people into believing they are experiencing divine visitations or astral travelling or any of the BS things that would convince people otherwise. Thats what Inception is About, fooling people to get them to help you by extracting information or by implanting it. Any version of manipulating someone can be done, make a man a monster, make a woman a whore, because neither can properly understand these feelings and thus think they are simply aspects of their own psyche and embrace them. My advice to anyone who thinks they are being manipulated is, don't do anything that you don't remember planning to do. like I pointed out before with that Doctor Who clip, the reason you might be doing something is because you don't remember being told to do it but if you Know thats a possibility it can help you define better what are your feelings and what are manipulated ones.
**I tried to link the video url at the right time, the clip is only like 10 seconds in reality but for some reason Steemit don't like doing that so watch this vid from 4:23, its just Mark III cloning but in the movie presented in reverse.
People who claim to be Spiritual Channels would definitely use Mark III clones as a means of fooling people.
