Great thread, this is something that has happened to me several times. There is one humerous story where I fell asleep while playing Neo Metal Fantasy once and my brother witnessed me constantly tapping the confirm button while my character was standing still on the world map. It's been happening to me more often recently too, while playing Final Fantasy VII, Opoona, and I think even Ys Book I & II! Definitely happens most with RPGs. This doesn't mean there is anything wrong with a game that I have fallen asleep to though!
