I have spoken of the “voices in our heads” as American Thought Control, who are the dominant faction of those humans who have the capacity to manipulate entangled consciousness, and navigate among our minds.
They pretend to be many things, from God to demons (or other entities), lizardmen aliens, “Nordics” and so much more.
These are humans who can manipulate and navigate consciousness, they are responsible for the “voices in our heads” driving so many mad from within. The “sentient plasma” claim is another game they play. My game was something very different, I was indoctrinated by Arizona Thought Control, the elite of the elite of the secret governance of Power haunting us all.
The Greys are real, and they are benign altruists (thank whichever God you pray to). They mean us no harm and are as good as irrelevant as far as human malady is concerned.
