Like when you've woken from a nap and you're irritable, and your hair wisps in your face are agitating, and you're not ready for noises yet...only not caused by a nap, and doesn't go away as you wake up more. On the bus you can't relax and you can't hardly look around, you hear every little sound and it seems like you can sense people watching you whether they really are or not. You deal with it by staring intently at your phone screen like there's no tomorrow, but whatever you're reading or looking at is not being absorbed at all, and you just got through a paragraph without remembering a bit of it. ADHD feeling, and it tends to kick up your adrenaline like there's no tomorrow. You might be in a quiet cafe or library, and you are irrationally angry and constantly about to throttle the girl across the way who won't stop coughing and clearing her throat frequently and sharply, and you know it's because of her headphones that she's oblivious to what she's doing.
