This isn't even a new thing...imagine how long they've been doing this kind of stuff to hypnotize people.

They even had a short hypnosis scene in there, like a mandala pattern with vaccines dancing around in a circle.

Mandala is an ancient sacred pattern for healing and improving the mind:

as a spiritual guidance tool, for establishing a sacred space and as an aid to meditation and trance induction.

But in this case they are using it for mind control.
