You are in a tunnel. As you go deeper and deeper, it keeps getting more strange, creepy, scary, terrifying, horrifying, and petrifying. And there will be strange sounds, or scary sounds that will make you become paranoid. And as you go even more deeper, there will be humans. But they will start acting more and more strange, and creepier as you go deep. As you go even deeper, there will be scary monsters. They get more and more hostile the deeper you go. The deeper, the scarier.
