You pass out while you noticed the machine in front of you, and landed on one of the conveyor belts that would take you into the machine where the cows would get milked. The robotic arms that were a part of the machine noticed you on the conveyor belt, and grabbed you, while stripping you from the clothes you had on.
The machine's arms placed you back on the conveyor belt once you became completely naked, and placed your hands and feet inside the hoof locks while you continued to sleep. Some scientists noticed you on the conveyor belt, and tried to wake you up, by sounding the alarm. You manage to wake up, but a VR helmet slipped onto your head before you could actually see what was going on. All you could see was a meadow full of grass, while a voice blocks out the alarm, and mind controls you.
