Just wondering whether those reptilians actually know that they are reptilian and different from us real humans?
Yes, they know. They have to maintain the mind control over others to keep their attractive image. They slip sometimes and then you can visibly see their image disintegrate… especially in crowds.
Is it inherently impossible for another to be able to override the strength of their projection, their mind-trick?
Part of it is that we don’t expect it, we’re not trying to override it. And as I’ve mentioned elsewhere, this is why the reptilians have avoided infiltrating Chinese society. China has a far larger number of Crystal Children than we realize. Their minds cannot be fooled by the mind-tricks reptilians have used.
