I dreamed an alien nation had a food shortage and had to search other planets to food. They found earth. But instead of looking at the crops and farm animals, they decided that humans gave them all the essential nutrients they needed. They didn't understand we were sentient beings. They thought of us in the same manner that most think of fish, chicken, or cows.
I don't have tv, but I read news stories, in this dream, that there were many reports of missing fat people. They were sneaking in the middle of the night looking for their "food." The bigger the better. The world's heaviest people went first. Then, months later, a few over 300 pounds. Weeks later, a few more until all those over 300 pounds were gone.
Finally the world leaders understood all their beloved big people were turning up missing. First it was reported they ran away (yeah, ok). Then they tried to understand how all the big people were leaving their homes. They just disappeared. Finally the authorities realized this was an attract to extract those with physical substance from our planet. But why (duh)? Everyone over 185 pounds turned up gone. Fat kids, moms, dads, wrestlers, football players, police officers, teachers, doctors, nurses... Everyone, except (even overweight) pregnant women. From all countries.
There was a worldwide plea to loose weight! Save your lives, lose weight.
You never know, you might be just big enough to feed a family of 5 on another planet, for a week. With garnishes and dessert, of course.
