Events in the order they happened. No jumping back.
Events are never simultaneous. They always have an order. Even in real life you process events one at a time.
The reader's attention is where you put it. The sharper you render something the more attention they'll pay to it. Blur the places you don't need them to notice.
The reader wants to trust you. The reader wants to stay in the dream.
Tension keeps them reading.
Payoffs are sweeter the further they are from the setups. More tension.
Scene-sequel. Motivation-reaction. Tension-release.
All rules can be broken, of course, if you know why you're breaking them. But I ain't at the rule-breaking stage.
