You are happy. that is good. And it doesn't really contradict a scientific mind, for as a scientist one should keep an open mind. It is not impossible that tortoises dream, if very unlikely. Therefore it is possible and therefore perhaps the tortoise in question DID have a nightmare. I am also always fighting against my own anthropomorphism. And often I lose. Which is fine. I love my tortoise whether she dreams or not.Yes, my anthropomorphic thoughts make me happy. Many traits in an animals that used to be called anthropomorphic have been proven to exist. So I'm going to go with it for now this does conflict a little bit with my scientific mind but I don't care.
As far as why the tortoise suddenly ran across his enclosure, could there have been a bug that him? I fed my box turtle a meal worm that must have bitten her because when she grabbed it she all of a sudden startled and ran backwards, yes backwards very quickly. So the only thing I could come up with is that she bit the tail end of the meal worms and the head and bit her. She made quick order of that warm though so that's good. And I never fed her that big of a worm again.
