The biblical meaning of snakes in dreams don’t really give a good foreboding. Right from the start, snakes are not treated well. They represent betrayal, treachery, and the most sinister form of evil deeds.
Always remember that in the time of creation, the devil took the form of a snake to tempt Eve to eat the forbidden fruit. That alone gave the absolute conception that snakes are creatures that are equivalent to deception and misfortune.
You cannot see any references in the bible that snakes have good attributes. Ever since the world of Christianity and even Islam has a bad connotation to snakes. Therefore, if you are searching for good fortunes, you must never make the snake as your spiritual totem or animal. You will not get anything good.
