He tried not to panic, but the world turned over on itself, and Peter thought 
he would vomit. He sent a hand toward the landing above him and dragged himself 
up. The doorknob was just above him. All he had to do was touch it. But it 
seemed so far away, as if he’d shrunk to a very small size. He glanced back down
the stairs and thought he’d never been so high up before. If he fell, he knew he
would never stop falling. He would fall and fall and stare at the bottom and see 
the impact coming forever.
