though, i have never had any such incident...but i wonder what would that moment be like..Snake
and i feel it depends on the snake, if it is poisonous stand perfectly still and do not talk, if it is hot out the snake will mistake you for a hot rock because snakes use inferred not color so if your surrounding is hot and you are hot and you do not move it will mistake you for a rock or something. if it is not venomous you can just run away it wont attack. if you do get bitten call for help and go to the hospital but if you get bit do not be scared or run because the venom will circulate though your blood faster and you will start dying faster.
