To dream of a mannequin represents you or someone else that cares about nothing except being noticed as a perfect example. A need to be noticed doing something the that others should copy. Wanting to be noticed by others as a perfect example.
Negatively, a mannequin may be a sign that you are too concerned about how you are viewed by others. It may also be a sign that you don’t care about anything except showing off or having people look up to you. A reflection of the importance you feel to make a certain impression that may have no substance.
Example: A man dreamed of falling in love with a mannequin. In waking life he was using a beautiful escort to lie to family that he had a girlfriend and slowly began to fall in love with the escort. The mannequin he feel in love with represented his obsession with keep the lie that he had a perfect girlfriend.
Example 2: An patriotic American man dreamed of seeing a mannequin shot up into the sky and blow up. In waking life he had been talking to friends about himself filing lawsuits against the Government for excessive corruption. The mannequin blowing up in the sky represented how important he felt it was to be noticed by people filing his lawsuit to prove his “Americanness” and how it eventually resulted in nothing as he was rejected by the courts. The dream reflected the futility he felt trying to be a perfect example of an American.
