Dreaming Lens: Were you speaking in public? Were you watching someone else speak? Where were you speaking? What was the topic you were speaking about? Were you comfortable or nervous?
Personal Focus: Speaking in public is challenging for most people. For some, that challenge is so intense that even the idea of it can bring on a terrorizing attack of anxiety. Since there is a literal connotation with this symbol to the act of speaking, a dream that involves this activity will naturally point to an area in your life where your communication is being put on the spot.
A person speaking in public is usually a figure of authority on some level. In this way, a dream that includes this as an image is probably expressing some area of your life where you are either in your authority or where your authority is being put to the test. This is especially so if you were the one doing the speaking. If you were in the audience and someone else was talking, use them as a Character Aspect of yourself to figure out what part of your personality has something to say. It could be that the power and authority you desire in life is speaking to you through your unconscious in your dream. (See also: Performing on Stage.) [1]
If the microphone is not working, it could suggest that there is a fear of not being heard.
If the audience is unruly and they appear not to be listening, your dream may be expressing the fear of not having command over your audience. [2]
