Dream

I've got this weird dream...

a guy carried 2 red wheels and ran on the road to stop a vehicle with 4 blue wheels and change it for him.

Chapter 1 - ...
Chapter 2 - Environmental factors
Chapter 3 - What you want (from them)
Chapter 4 - No! There's nothing inside here
Chapter 5 onwards - Individual factors

It's as if I've read a certain book whereby Chapter 4 is blank totally and the book seeks to explain something which I cant remember now and also I cant remember what Chapter 1 is about. These are the pieces I remembered after woking up from this dream.
