Just gotta say the whole shapeshifting lizard people thing is a disinformation campaign about what they truly are. They are human beings that have been parasitically infected by Vril parasites.
An ancient subterranean race of creatures that are physical manifestations of what we consider 'demonic energy'.
No back and forth transmutation, just a parasite that completely takes over the human body, kills the soul and operates from there.
The child killing, the kidnapping.. these aren't for pleasures it's the Vril way to stay alive. It's what they feed on for sustenance.
Everybody needs to stop with 'lizard people' troupe, stop with 'aliens' and realize that everything good bad and ugly is right here on and under the surface of our flat, solitary, terrestrial realm.
