A state of mind
A state of mind is like being so tired you think your brain is gonna fall out and your thoughts are just screaming at you to shut up and go to sleep.
I was in a state of mind after staying up all night watching Netflix and my brain was like 'no more, I’m done.'
My brother was in a state of mind after playing video games for 8 hours straight and he didn’t even notice the sun came up.
My dog was in a state of mind because he was so tired from chasing his tail that he fell asleep in the middle of the floor.
