This happened when I was living in northern Minnesota during the ’70s to the early ’80s. We had 4 tv stations to choose from. I turned the channel to PBS and watched something strange. A dad, mom, boy and girl sat like crash-test dummies unmoving at a table. The room they sat in (maybe a kitchen) had very little in it. A prompt would come up saying something like “wind”. A giant wind storm would blow through the room as the family just sat there and took it. Another prompt would come up like “quake”. The room would reset itself as if the wind storm never happened. The quake would shake everything out of place but when the next prompt came up everything would be back in its place. This would go on for many prompts. The only time the room didn’t reset was after the prompt “sand”. A foot of sand blew into the room and stayed there even after other prompts. It was almost like I was watching an immobile family subjected to various torturous conditions that were removed after each testing except for the sand. This might have been from 30 to 60 minutes long. That is all I know.
I also remember something on PBS during the same time period where a young good guy gets transmitted inside a TV by a young bad guy. The good guy pounds on the TV’s glass screen. The good guy’s girlfriend risks getting stuck inside the TV trying to save him but is able to get the good guy out. She traps the bad guy in the TV and they leave him in there fearfully pounding on the glass screen. It isn’t John Ritter’s film “STAY TUNED“. That too is all I know.
I hope my memory is correct and I hope you can help. The bad guy stuck in the TV had extreme fear and made the good guys look amoral.
