To dream that you have an abortion, suggests that you are hindering and blocking your own growth. You may be hesitant in pursuing a new direction in your life.
The dream may also be a reflection of your own real-life abortion. And thus serve as a way of healing from the trauma and working towards self-acceptance.
This dream may also be a message for you to take care and look after your health.
Also, to a man a dream containing abortion indicates failure in his kind endeavor. For a woman it is very clearly a health dream and may indicate her health is in some sort of danger.
