Betrayal
To dream of betrayal represents feelings of disappointment or being let down. Having wasted your time trusting someone. Unexpressed or "bottled up" feelings about being deceived.
Negatively, betrayal may reflect a heightened degree of suspicion you feel for a person, relationship, or situation. Insecurity about major commitments.
Alternatively, betrayal in a dream may reflecting feelings about self-betrayal due to bad choices. Feeling that you gave into temptation. Giving into last minute temptation after expecting to be impervious to temptation. Self-pity or feeling sorry for yourself.
Example: A woman dreamed of being betrayed. In waking life she was on a diet and gave into temptations to eat junk food. She felt that she had betrayed herself and was disappointed in herself.
