I've been re-reading this over and over and I'm not sure what you're trying to say. But didn't you simply close your eyes (fall asleep) maybe when the sun was coming up and you woke back up a few hours later when it was fully daylight? I understand what he's saying. That's how it felt for me that one time I fell asleep for 24 hours. The atmospheric lighting changed because it was obviously a different day... and what felt like a momentary eye shutter felt like everything changed in that instant. I've had that a few times, Feels like 5 mins went by but it's morning suddenly
