You say you were going through a phase of terrible sleep. Would you say that particular night of sleep was worse than your average night of sleep during that phase?
Basically, it felt like the body had gone through the motions of sleeping, but the brain felt even more tired than usual. It felt very confusing, as all measures seemed to indicate that I had slept for a solid 8+ hours, but I felt less rested than when I'd gone to sleep. It's like someone hit the "pause" button on the brain processing cycle, and sleep never happened for the brain.
The idea that quantity sleep is better than quality is something I see a lot of people im married to struggle with.
Exactly how many people are you married to anyways? ;-D
