1968 my alien abduction took place on a lonesome county road in Georgia. The events were breathtaking and shocking! The alien greys used a silver rod that knocked people unconscious when they were touched by the alien rod. The alien weapon seemed like a harmless weapon of choice for the aliens to knock out their abduction victims before capturing them similar to an animal dart that is used for knocking animals of the wild unconscious while they are moved. The alien rod acts like an invisible needle prong and inserts through the skin to the body to absorb a anesthesia like shot that knocks the body unconscious.

I was abducted also in 1968 along with other abduction victims and experienced the Medical Beams in which covered through aurora light rings that circled through my body. The Medical Beams seemed to be taking blood DNA molecules and projecting them through lazier pulsar beams into a machine that coded my DNA blood molecules and reshaped them through biogenetic and kryogenic experiments conducted by the aliens. So, your story of Medical Beams make sense to me as an abduction victim. For me, such accuracy in describing this Medical Beam I would like to add that the rest of what you say or theorize may also ring true.
