I walked in on my dad watching an 80’s / early 90’s scifi movie, i only saw a few scenes. I remember that it involves another dimension or a dream world. one scene where the main character sees crying people voluntarily go onto a conveyor belt that feeds them into a giant meat grinder. I seemto remember it invokving the idea of punishment for some sort of sacrilege. It may also involve a “Shrike” like ‘god’ of death
“Mindwarp” (1992)?
Here is a trailer.

Sounds kind of like “Soylet Green”.
