chipmunk sounds

Today my body woke up at 7 am. I was pretty excited and thought, "Wow, I'm going to be so energized by the time I get to class today." I guess that's what happens when you go to sleep at 11pm instead of the normal 2am. After class I came home, took a nap and woke up to my own mouth making noises! How silly is that? It sounded like I sounded like a chipmunk eating! Oh dear, the signs of getting older perhaps?
