I am tested by multiple agencies but when I read about others people perspective I dont find much similarities. First of all I think I was used for purposes not just testing ie I was brainwashed into thinking of myself as an agent and when I told someone to torture terrorists they could use my persona as a scapegoat(for CIA) or they made me learn economics and math and I made dicisions on the stock market to grow their black budget(for Mossad). If you name voices voice to skull than I should introduce the image to skull technology too, the two of them combined makes it hard to actually know the difference if you were there or it was just like a VR test. Also theres the dream hijacking when in your sleep they test your unconsciousness and can be trained very effectively. Personally I was tortured several times but the worst part began when I realized this thing is not a conteo so they did several mock execution and forced suicide(these are known psychological torture methods), also it is possible to feel and I was raped by Mossad. And a quick tip: learn to be good at metacognitive thinking because they can manipulate and control easily if you cant differentiate your thoughts and others via this technology.(I had a short time that I believed in gang stalking but they implemented those thoughts) i dont think they follow you in physical presence because with this method they are able to see what you see and hear what you think.
