I confess that I slept in the train again! I came from my work and was really tired. When the time I woke up, I was at the 6th train station after the station that I suppose to get off. I always come to that situation, but this time it was really scary. It was 12am already and there was no more train to arrive at that station. I was so alone in the station, and it was so cold. I didn't know what to do. Good thing I had $1 in my wallet. I called a taxi and came home safe.
