What does it mean when a guy friend stroking your arm while your sleeping?

Anonymous
I was sitting next to my guy friend today on the bus today and I fell asleep next to him. I was on the window side so I was leaning against the window, and he was talking to people on the bus. But then suddenly I feel someone stroking my upper arm. I open my eyes and it was my friend and I told him I was just really sleepy. And then when we got off the bus he said bye to me and that he hopes I have a great weekend. Why did he stroke my arm? Does he like me as more than a friend? By the way, we are fifteen.
