Snoring!! Was I?

Today on my way back to house from my course with the tube, I had a strange incident. I was very much tired as usual, I do get tired everyday after continuous 5 hrs of lectures in estranged language. I have to travel almost an hour to reach my house, well for that I make sure I get a comfortable place in the direction of travel for myself to sit. The train has not left yet, then came a typical German guy and sat next to me. He looked at me and we exchanged greetings, well that's a common practice here that even you greet the strangers.

Probably, I was very much tired today than usual and I did not realized wen I did fall asleep may be deep asleep. I woke up little later to realize that the guy sitting next to me has already left. Well, I slipped back to my unusual deep slumber. I could only wake up after I think I had enough of it and I realized that the train has halted somewhere. It's a halt one before mine. Then I realized the guy who was sitting next to me was getting off and he gave a wry smile at me before he was off the train. I did not understand, why did this guy who was sitting next to me moved away to a different place and why did he give a wry smile wen he set off. Well, I could not figure it out yet exactly wat has happened.

Was I snoring that he got disturbed or irritated with it and moved away from me?????...........
