Once we arrived, we left for the beach. As time goes by she wants to go home and I came to us because we couldn't find a place to go for a walk. Therefore, we turn around and head back to Dothan. I had a feeling she was starting to get tired from driving, so I asked her if she wanted to pull over and rest, she refused. We keep driving and I keep asking her if she wants to make stops and what not, she kept saying no, so I ask her a few more times before I stop asking. So I immediately fell asleep getting tired all of a sudden and when I woke up from my nap of a few minutes, I turned over and she fell asleep having control of the steering wheel. I go to wake her up and when I do she goes crazy, swerving into the traffic island, then swerving harder and we roll for 30 metres. I didn't have a seatbelt on during that accident, it was the only thing that kept me sitting by pushing me into the seat. Luckily, the vehicle landed upright and I was able to force open the door. Instinctively I immediately went to check on her and make sure she was okay, and at first she was really freaking out seeing me hyperventilating, crying and asking if I was okay. When I finally calmed her down, the situation was a little better, somehow my phone survived and I called the police. Sitting there for about ten minutes in the dark with only the moonlight illuminating our surroundings, the police finally arrived. I'm just wondering why and how this happened
