Being "world blind," is the feeling of confusion when you have barely woken up. It can happen at anytime of day.
Person 1: *wakes up, lays in bed, and thinks* What's going, what time could it be...*checks phone* 12pm?! 20 missed calls?! *phone rings & picks up*
Person 2: Hey budddy, I have to tell you something super important, it's about last night...
Person 1: Not yet dude, I just woke up, I'm still world blind, and confused.
