I don't drool in my sleep; not sure why, seems that I would every once in a while, but it doesn't happen. I do injure myself though, tend to wake up with odd bruises and cuts sometimes. Still, morning drool is cute, most people know my stance on it.
I drool sometimes when I sleep. Not very often. >///< It gets on my pillow when I wake up and it feels wet and weird... So I flip my pillow over and then go back to sleep.
