An outcast or wandering person can symbolize a spiritual oppressor or being cast-out from the presence of God, Gen. 4:12
One who sponges off others; may symbolize someone of similar character
To dream that you are a bum represents emotions relating to loneliness and solitude. You don’t feel as if you belong. You find it very difficult to handle the various issues and situations in your life.
To see a bum in your dream implies that you should find the ambition and drive to improve your current situation.
