A dealer is a person who is giving or selling something to someone. In the Bible, Jesus counsels us to make deals with Him in the form of purchase. Dreaming of buying could represent paying the price for spiritual things.
Positive: If someone is giving you things or gifts it could represent God’s grace, favor, and blessings on your life.
Negative: Dreaming of a dealer who is lying to you or scamming you could represent one’s treachery, deceitfulness, malice, or ill-intent.
(Revelation 3:18; Genesis 33:11; Romans 12:3; Genesis 19:9; Malachi 2:16).
