Last time I went skiing, I had to get up at 5:00 in the morning. I knew I couldn't do that, so I slept with my skis on. My ride came at 5:30 in the morning, couldn't wake me up so he carried me out of the house, put my skis on the roof rack of the car, and drove to the mountain. Seventeen miles later, I woke up out of this incredibly bizarre dream that I was skydiving horizontally. I'm sure this has happened to you.
