Thank you for sharing your dream with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
Sean means God is gracious and the meaning of your dream might have to do with the meaning of your friend’s name. This dream could be prophetic in nature and the only way to know with all certainty is to wait and see what happens. Alternatively, it could be an encouragement that no matter what you are doing currently or waiting for remember that “God is gracious.”
