Some people have nightmares about being naked, falling, missing a test, etc. I have nightmares about being late for work.
I'll wake up at 1 am in a sweat thinking I've missed my shift. Any time a phone wakes me up, I instantly assume it's the pool wondering where I am. Some nights, when I'm especially exhausted, I'll toss and turn all night thinking if I fall asleep, I'll miss my alarm. In Georgia, I kept Irene awake one afternoon because I was tossing, turning, and whimpering. Guess what I was dreaming about? Being stuck in traffic when I was supposed to be teaching lessons.
I cope with this by getting ready very, very early. I set my alarm for an hour and fifteen before work when I know I only need 45 minutes. When I open, I'm usually at the door by 5:07, when the guy with the key doesn't show until 5:15. (How he times it perfectly, I'll never know.)
Right now it's about 12:40, I'll be leaving in 5 minutes so I'll be at the pool with a whole 10 to spare.
