If you have seen a snake on my back in your dream: If some changes need to be made, try to make the changes you want, not the others. To see a snake on my back in a dream denotes being together with an enemy who has financial and moral burden, increasing problems, suffering and falling out of favor. If a snake stings on my back in a dream, it means that bad luck will haunt you and you will be harmed by the enemy, you will be sad and your reputation will be destroyed.
