A dream of being betrayed is read as insecurity and fear of loss, far more often than as a fact. Tradition takes it as a question about trust — including trust in yourself. Dreaming that a partner is unfaithful is one of the most common dreams, linked to feeling less seen or less certain in the relationship. A friend turning against you points to a fear of being excluded. If you are the one who betrays, dream books read guilt or a choice you feel conflicted about. It can help to notice where in waking life you feel unsure of your footing with someone.
