Just wrapped up season 3 of stranger things and couldn't help but notice some similarities the Mind Flayer (Shadow monster) and the Demogorgons shared with the Reptilian/Vrill conspiracy. From taking control of a hosts body via brutal physical entry the mind flayer could then manipulate and over-ride the hosts body an have them carry out heinous acts such as Billy murdering and bring bodies for sacrificial ritual to the Shadow monster (who would also take the form of some giant fleshy alien demonic beast.) This is very similar to the conspiracy of a Reptilian race secretly controlling the elite (Blake eye club) The conspiracy goes that especially in Hollywood, the black eye club is a group of individuals who have appeared to have a black eye which serves as a mark that they are now under control of these entities. It has also been said that these reptilians feast on humans which is part of the reason for so many Americans vanishing off the face of the earth much like how the Demogorgon would feast on humans in the show. I believe Eleven represented free will and the only thing that stood in the way of the Mind Flayer taking over the world. There is a scene where while remote viewing, Eleven comes face to face with Billy who says they are building an army to take over the world, much like how I believe the elite and reptilians are building they're forces as we march towards a NWO totalitarian rule, but first they much conquer the natural free will of humans. We all know these people love hiding subtle clues in plain sight, why not take advantage of the largely teen and young adult audience and hide dark content right in front of their faces?
