Dream about someone setting a fire signals your intuition and the sensitive side of your personality. You tend to take on more than you can handle. You have cooled off from some heated argument. This draws attention to some love triangle or some relationship conflict. You want to make your presence known and stand out from the crowd.
Someone setting a fire dream is a hint for industry and hard work. You need to keep your distance from some matter or situation. Something or someone in your current life is bringing out similar feelings you felt during a relationship with your ex. It expresses your intuition. You are prepared and ready for the task at hand.
If you dreamt about someone setting a fire:
Let the genius within you come out and play. You may feel like some sort of inventor who has wild ideas that could help to revolutionize the future. Bring these ideas into the open and see what kind of response you get from the people around you. Cutting-edge concepts are likely to appeal to you the most. These are the ones that you should pursue and follow through on if you can.
