  • Since 1986, I have been sensing and perceiving people spying on me, constantly. Are such people using your new camera technology, at http://interestingengineering.com/watch-photons-moving-slow-motion-1-trillion-frames-per-second/ and https://youtu.be/JWDocXPy-iQ, which report an ability to "see people around corners," and https://youtu.be/mfgsQX78hg8, which reports ways to advance lighting effects? How do I make such people contact me?
