One who is controlled by others
To see a dummy in your dream means that an important component is lacking in a key relationship in your life. You are feeling unchallenged and unfulfilled by your relationship.
The dream may also represent how you or someone else has acted foolishly in a certain situation.
1. Feelings of powerlessness, being ineffectual.
2. An important relationship is starting to feel one-sided.
3. An aspect of self feels useless.
Dreaming of a dummy is an omen of your failure to succeed in an enterprise where ordinarily good judgment would help you out.
