Regarding sleep paralysis I was reading Volume 2 of the declassified
UK UAP files and on page E1 of part A I saw something interesting about this phenomenon and UAP radiation.
"At the time of vehicle failure several reports (Canada) have resulted in apparent temporary paralysis of humans until the nearby object moved away. It is possible that some muscular control (motor-control) nerves can be affected by electrical potential. This can be replicated by medical scientists. One explanation is that either constant or pulsed microwave, coupling into the nervous system may cause this affect. Pulsed interference with the human system is possible because of the 500 milliseconds muscle relaxation delay. "
