Express your own negative elements undermining your relationship.
This dream may be revealing your worries and concerns in real life. Maybe you have the feeling that something bad might happen to your husband or boyfriend.
At a symbolic level, the snake biting your partner may be a representation of your more harmful traits or behaviors affecting your relationship with your significant one in real life, such as bad habits, harmful emotions or personal defects.
In some cases, your spouse or romantic mate could just be a dream character that represents a business partner or a co-worker with whom you spend a lot of time sharing a common work project. Pay special attention to this interpretation if in your dream, for some reason you already know or feel that the character is your “husband” (or boyfriend) despite having a different physical appearance.
