Dreaming about a snake or snakes can mean that you feel someone in your life is manipulating you or trying to get something for nothing. Snakes are often thought of as sneaky, cunning and evil. This may stem from the bible as the first sign of evil was a snake tempting Eve to eat fruit from a forbidden tree.
Since then, snakes have been thought of as evil and dirty. To dream about you being a snake can mean you feel you’re taking advantage of someone or some people. To dream about killing a snake or running away from one can mean you want to remove negative people from your life.
