You're panicked, sore, and scared. Home is where you feel safe. Going there seems like the obvious choice, even if you have to walk. You head back down the highway in the direction from which you just drove prior to wrecking your car. You make it about a mile before you see a police car whiz by with lights flashing. It's only a few minutes before they're back to talk to you. You know what's going to happen already. It's exactly what you expected, isn't it? You're going to get charged with killing this man and it's going to wreck what you currently have established as your life and, more to the point, it's going to ruin your dream and wake you up.
