Sleeping in the train

The way I sleep in the train, If I am not careful, I will find myself at the airport. I normally board the train to Georgia State University or Grady Memorial Hospital. Today, I boarded the train from Grady heading back to Doraville Station. I was very tired because I have only had two hours of sleep this morning before leaving my house. Immediately I sat down, I dozed off. I remember waking up at Lenox train station when the train stopped, but I went back to sleep again after that. I am sure I was in the train another 10mins after it had stopped at Doraville station before I realized that the train was not moving anymore. I woke up confused as ever, saw the Doraville sign, but was not able to figure out where I was. It is not funny at all because this is not the first time. I am scared that the third time, I will be at the airport.
