Adder Snake – An adder or snake is a dream symbol of a person who is untrustworthy. Likely this is a person who is in a close or influential position for you, and whom you would not expect to betray you. This makes the betrayal more devastating when it happens. Do not allow this dream to make you paranoid. It may be a warning that someone near you is not trustworthy, but it may also be a sign that you are beginning to question a close relationship, regardless of whether that person is actually trustworthy in real life.
