Thank you for sharing your dream/experiences with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
The former is probably highlighting you about some aspect of the individual to be prepared and/or pray for. The content of the dream could also hint at what the Holy Spirit is trying to inform or alert you about. Next time pay attention to what the dream is showing.
The latter might have to do with the essence or meaning of the name of the celebrities.
