Intimidating is the act of making one timid or fearful. It could also mean to compel someone to do something through threats.
Positive: Dreaming of not being intimidated by an enemy could indicated that you have the heart to endure persecution for the sake of the Gospel. It could also represent that the Lord has given you strength.
Negative: Dreaming of intimidating someone could represent that you have no compassion for others and are manipulative. Dreaming of being intimidated could also indicate that you have a weakness and fear in your life.
(Ezekiel 34:4; 1 Peter 3:14; Acts 4:16-20).
