What’s going on? I’m in the back car of a roller coaster at the top of the climb, with the front rows already giving themselves over to gravity. I can hear those front riders screaming and know my own scream is only seconds away. I’m at the moment you hear the landing gear of a plane grind loudly into place, in that instant before your rational mind tells you it’s just the landing gear. I’m leaping off a cliff only to discover I can fly… and then realizing there’s nowhere to land. Ever. That’s what’s going on.
