A while back, I wrote about the snake-eyed ones - the people one meets whose eyes have the hard, calculating, hypnotic, manipulative stare of snakes or lizards (or dragons).
On the whole, these are probably people who are 'demonically possessed' - who have invited evil spirits into their souls, on promise of gaining some worldly goal (e.g. money, power, sex, sadism).
Zombie eyes are another, and probably more common, phenomenon - perhaps especially among women. These are dead eyes, eyes that utterly lack agency, free will, inner motivation.
While snake eyes seem to indicate the presence of a purposive evil being in the soul; zombie eyes seem to indicate something like mind-control. That person's real self has been switched-off, suppressed, buried... and their actions are being controlled...
The dead eyes show that the mind has become a conduit - and has no source of being in-itself. The soul has been bypassed and the body, the movements, the emotions are all externally-driven.
The cause of zombie eyes could be - at the extreme - a mental enslavement imposed on an initially-willing victim; or it could be (in more susceptible persons) simply the result of living in a bureaucratic world at work, and a mass/ social media world during leisure... many people simply open their minds and let the world flow-through.
Such are these End Times... On the positive side, it can be quite easy to identity the as-yet un-corrupted - those (few) who are not the allies, servants or slaves of the demons. One meeting of the eyes may be enough - the open-hearted gaze or smile of a child, for example. How few adults one meets who have that clarity and goodness of soul! - yet there are some.
