It was said that I was being sent back to the torture chamber.
I see a spinning machine and chairs that we are strapped into. They produce jolting vibrations, shaking to the point where you have no control over your body movements.
Other experiments with EMF's were conducted. Finding the correct frequency and sound waves.
I would be asked what was inaudible, what was audible. When they were talking to me and when I was intercepting messages that were being sent from remote locations.
