Haha, this is funny. I have fasted in the past (on a CW diet!) for 3 days and I never had that feeling that I can recall. I do however, have those weird dreams, errr... nightmares actually! I was dreaming last week that I was at a waterfall and for some reason I was hanging upside down on some sort of amusement ride or bungee or something and the dropping movement of the ride made all my teeth fall out and and I was complaining to the company afterward and they were telling me I couldn't get my teeth back! I always have these types of bizarre, scary dreams.
