Faithless in a dream can represent feelings of insecurity, instability and the need to feel better about oneself. There are different causes that might lead to these emotions.
A person’s faithlessness in a dream may signify feeling betrayed by someone they love or believing themselves to be unloved by others. Persons who are experiencing these emotions may also have been made to feel like they were not good enough. This can happen when parents do not show support with their children or when friends do not offer any encouragement or positive feedback.
It could also mean that the person is no longer sure about their earnings potential, financial stability, or future career prospects. These uncertainties would likely lead to feeling abandoned, feeling forsaken by some thing that one would normally trust.
