The following quote resonated with me. However, the article is primarily about the Gnostics and the Archons.
To the horrified astonishment of Dr. Castaneda, the elder sorcerer Don Juan explained how the human mind has been infiltrated by an alien intelligence: “We have a predator that came from the depths of the cosmos and took over the rule of our lives. Human beings are its prisoners. The predator is our lord and master. It has rendered us docile and helpless. If we want to protest, it suppresses our protest. If we want to act independently, it demands that we don’t do so.”
The late Harvard professor John Mack wrote that “a number of shamans with whom I have spoken, from native cultures of North and South America, Africa, and Australia, know of, or have had encounters with, beings that have properties much like the grey aliens that visit abductees in the United States and other Western societies. Each culture has its own name for them. According to these shamans, beings of this sort have been around for thousands of years and seem to have a great interest in the face of Earth, functioning as its scavengers or protectors depending on the particular shaman's experience or point of view.”
The above reminded me of two experiences I had several years ago. One, involving a green reptilian type entity (though not the typical alien-reptilian often portrayed as "the Reptilians") and the other, a cape used by a Central American shaman.
