A microphone is a device used for amplifying sound. Dreaming of a microphone could represent a voice or authority.

Positive: Dreaming of a microphone could represent a voice or authority. It could represent God trying to tell you something about your life or ministry.

Negative: If you see someone taking a microphone from someone else or using a microphone that they shouldn’t have, it may represent arrogance and pride or someone wanting their voice to be heard. It could be a wrong influence.

(Matthew 10:27; John 12:49).
