Yeah, but what is it?

"Well John, it's a machine that exentuates...certain aspects of a person. It's based on their subconscious desire, and changes certain parts of their psychology and biology. It could be revolutionary!" Your dad sure was enthusiastic about this. The machine seemed kind of fishy though. Was that technology even possible? What if it made a mistake?

After a minute or two of tinkering with the machine, he ends up getting it working. "Go on, go on, enter!" You're a little skeptical, but you figure you should trust your dad. Nothing could go too wrong, surely. His inventions haven't been too bad before. So, you enter the machine, as he closes the door. Theres some dark tinted glass so you can still see him though, as he starts to mess with the controls and give you a thumbs up. As he does, the machine rares to life, as you start to feel drowsy. The last thing you see before you fall asleep is your dad with a concerned look on his face.
