I had a dream once about eating sausages that did that. Couldn't look at a plate of Cumberlands the same for quite a while afterwards without hearing their cries and pleas for mercy.
You know, a buddy of mine back in high school had tried salvia divinorum, back when it was legal. You're supposed to close your eyes, chew the leaves and have mild, useful hallucinations for about an hour, but you can also buy it ground, smoke it and get blown out of the universe for 15 minutes. He did the latter.
Well it messed him up so much that for months afterward he started
having dreams that he was on salvia, even though he never touched the stuff a second time. He worked as a McSlave around then and he had one dream that he went to work on salvia and the fries in the fryer were writhing and screaming "Noo! Don't eat meee!" and wriggling trying to get out of the oil as he submerged them. When he took them
out of the oil they would actually "run" up the sides of the basket and try to escape across the floor/counter. He tells me he could hear but not see his boss yelling in the dream, and he couldn't catch the fleeing fries because the salvia hallucinations were sort of tailored to foil his attempts at planning/focus etc.
He woke up, went straight into McDicks and quit that very day. When another buddy of mine asked me to babysit her and a mutual friend while
they tried salvia a week later, I respectfully declined.
