Spiritually, to be a traitor is to deny our basic beliefs. We do not have the courage of our convictions. When in a dream we are betrayed by others with whom we thought we shared beliefs and discover that they have let us down it would mean they are traitors to the relationship. To dream of a traitor suggests that we are subconsciously aware of deviousness. This may be in someone else, or it could be a part of our personality that is letting us down. We may feel that our standards are not appreciated by others.
