It was time for Adams to go on his road trip, and his mom was begging him not to go. But he finally left and she told him to be safe.
Adam started his road trip and went over a bridge, he saw a hitchhiker with a bag and swerved. Adams was fine and continued on.
Adams car broke down and as he pulled up to the mechanic he saw the hitchhiker again, so he asked the mechanic if he usually saw hitchhikers and the mechanic said "no". But Adam kept seeing that hitchhiker.
Adam saw a girl on the side of the road, and offered her a ride to make sure he wasn't alone anymore. Adam once again saw the hitchhiker, but this time tried to hit him. The girl didn't see the hitchhiker and thought he was crazy, and left.
When Adam finally got to New Mexico, he called his mom and she didn't pick up. Someone else did, and said she was in the hospital because she was in shock.
Adams mom was in shock because, Adams died. He was confused because he thought he was alive. But he was really dead the whole time.
