I've actually stepped on a water snake without it moving. It was definitely alive when I grabbed him...

Who the hell is Pat?
"Pattimuss doesn't run, he prances most delicately, like a beautiful but sad fairy, winged and capped, curly toed shoes on each foot, dancing on dewdrops while lazy crickets play soft music for him to keep time by...." - Wes
First off, do snakes sleep? I think no one can know for sure. Maybe if they did some kind of brain scan, but that wouldnt work, for it would surely wake a so called sleeping snake. In all my reading and searching for the answer, all I ever find is, that snakes are close to the ground and have covers that shed to protect their eyes. Yah......
I know that, so answer the question!!! No one can give the answer. For all we know they could be aliens....LOL
