Well, the dream had no industrialized mass meat production with horrible suffering, so it was not precisely a horror dream or nightmare. It was still odd though, because I almost never dream about eating meat after having been a vegetarian for almost two decades now. But in the dream the food was still delicious even though you heard the thoughts of a surviving goose while eating another. But yeah, I suspect if that really happened with eating meat a lot more people would become vegetarian, or at least the meat production would be a lot better...
