To dream that you are yearning for something or someone indicates that there is a void that is lacking in your waking life. You are suppressing some old habit or denying yourself of something. What are you yearning for in your dream? You need to fulfill this void.
To dream that you are saying “yes” symbolises reaffirmation or acceptance of a condition, situation or decision. The dream may also be giving you permission to do something that you are having doubts about in your waking life.
