oh! that happens to me too and people told me it sounds like heavy chains being dragged against the floor. they are also impressed how i wake up with any teeth at all.
A mill AND gallopping horses?? At the same time? 3D surround sound?? XD
actually a weird mix of both - the sound of a mill in the rhythm of galloping horses; Slightly Monty Pythonesque.
I: I literally laughed out loud at your comment. Heavy chains being dragged against the floor is a pretty awesome description. Yeah, it's a miracle we have any teeth left...mine are pretty worn down and flat. Maybe it's evened out because I had big mousy teeth as a kid. But still. It's also scary to look at the wear and tear of my plastic night guard. T: Yeah, and poor G sleeping next to it. HAHA. Nightmares!G: I probably should wear my night guard every night, even if IS the most unattractive thing in the world. Oh, and it makes me drool. A lot.
That's still impressive. And scary.
