(Those "surreal" movies in psych class creeped me out.)

You just get a "feeling" for subliminally loaded and/or propaganda
media.
The John Walker Lynde (the American tried fior treason for fighting for the Taliban) interview caused many people to feel that there was
something "just not right" about it, even those not familiar with
subliminals.

"Subliminal Seduction"
"Media Sexploitation"
by Wilson Bryan Key

Two books that will forever change the way you look at ANY mainstream
media, especially advertising and news video/photos.

Monet even used subliminal manipulation in his works, "Water Lilies"
is a masterpiece of subliminal construction.
It was a secret of master artists for centuries. Just lightly etch in
a single "trigger word" (seks, sex), invisible to the unsuspecting
eye, and even mediocre works will fetch a small fortune.
"I'm just DRAWN to it somehow." "I find it strangely compelling."

It became a "secret" technology adopted and developed by industry over
100 years ago.

Remember that "Dirty Trick" Bush campaign ad where the word "RATS"
separated from "Democrats?" Big scandal, nothing came of it. Still
pictures are much easier to read than video, unless you examine it
frame by frame.

You can see how effective subliminal penetration can be not only in
advertising, but in social conditioning as well. The propaganda that
you DON'T see is the most effective.
And most people don't see it.
