The other night, I dreamt that my sister was chased by this guy in some kind of forest. I was trying to catch him but he was just too fast and annoying.
This little guy has been put in a bag and kept in a closet. Unfortunately, he also has been forgotten there. He became a monster.
Farmmonster. That man and all his farm (with the animals) have been swallowed down in a giant hole created by too much use of chemicals. When people realized that, after a few weeks, it was too late, he has become a monster.
