A dummy is a word used to describe someone who is a non-entity or an object. In dreams, the meaning of a dummy can be interpreted as something that you do not want to deal with in your waking life.
Followed by a dummy in your dream means that you are not confident about your life, or lack of self-confidence. You might feel like you don’t know what’s going on in life and that there is no direction for where you are heading.
The symbolism of the dummy in your dream might also mean that you are feeling inferior or inadequate as a person because there is someone else who seems to be more successful than you.
