A dream of emptiness is a representation that something is lacking or missing or falling short in your life. These feelings can be associated with loneliness or failure in your life. The conditions can be derived from a stale relationship at work or lackluster position at work. It can be a shortcoming of your expectations and the feeling that all your efforts results to fruitless tree.
Dreaming of an abdomen means you have a hunger to succeed, and fulfill a destiny. Currently, there is an amount of emptiness that you are aware of, and which makes your mind wander in the waking hours.
Accept the task of your destiny by writing it down, and pursue it everyday until the abdomen dream is no more.
