A wanderer is a person who travels around the world searching for their sense of accomplishment. This person aimlessly travels, sometimes without a purpose.
Positive: Dreaming of a wanderer or of being a wanderer could represent that you are searching for the Lord with humility and as you seek you shall find.
Negative: In a dream, a wanderer could symbolize that you are not stable in the Word of God and that you are aimlessly wandering. It could represent that you are not willing to do the work that is required, but you would rather just coast through life.
(Matthew 7:7-8; Proverbs 20:6).
