I guess I was about 11 or 12 when one of my friends was sleeping over at our place. I woke up in the middle of the night, I don't know what woke me, but I saw my friend sitting up on his mattress. "What's up?", I asked him. He said "I hafta go home", and he stood up with eyes still closed. I told him, "Hey, you're sleep-walking, wake up and get back to bed". Then all of the sudden, he just takes off and runs at a closed door which took to the hallway. *BAM!* And he didn't even wake up! I got up and went to him, asked if he was ok and all. He was just mumbling something and holding his head. I put him back to bed and got back to sleep myself too. In the morning when I told him about this, he was sure I had made it all up.
