Humming – Dreaming about humming is a symbol of covert or even tacit communication. It may be a signal that you are telling other people things about yourself that you do not mean to, by wearing your heart on your sleeve or being easy to read in your facial expressions. It may also indicate a desire to communicate something to someone else, but an unwillingness to say it openly. You may wish them to know that you feel a certain way, but hope that they will discover it by observing you rather than needing to be told explicitly. Humming can also be a symbol of expressing joy.
