Any issue, any problems, or nagging worries that are deceptively small that have come back to bite you in the metaphorical sense? Maybe the snake represents something toxic in your life that, again, you maybe didn't think was relevant until the last minute. This house you were hoping to move into: Is it something that could potentially come to fruition or is it just a dream. Maybe the worry revolves around the house in some way?

Hope that helps!
