Exile in a dream suggests that you feel alone, or that you have been left behind by others on the journey of life. It could also symbolize your desire to be free from constraints, restrictions, or old patterns of behavior.
A dream of exile is representative of not only the individual who is banished but also a representation of people who are marginalized, rejected and excluded from social groups because they are perceived as outsiders.
Exile in a dream represents feeling abandoned or outcast. It may also mean a loss of power and something you once cared about is slipping away.
A person who is dreaming of being exiled from their home may be trying to escape the troubles they are experiencing in their waking life.
