To dream of an antenna represents emotional or psychological receptivity. How open you or someone else is to accepting new ideas or thoughts. Feelings yourself or others being able to easily relay information to others. You or someone else that is waiting for orders to follow. Communication that is effortlessly understood or “just obvious.” Partnership communication that is easy.
Negatively, an antenna may reflect feelings about all your actions or thoughts being easily monitored. Feeling that parents, authority figures, or enemies can easily communicate to each other. Feelings about yourself being easily controlled, observed, or outsmarted. Feelings about enemies easily making you feel stupid. Feelings about all your secret plans being easily communicated or understood by competitors. Jealousy of being too obvious to others. Frustration that it is too easy to understood how to outsmart you.
Example: A young boy dreamed of seeing white surveillance vans with antennas on the top of them. In waking life he was concerned about people who were keeping close tabs on him easily telling on him. The antenna in this case may have reflected his feelings about how easy it would be for the people keeping close tabs on him to relay information about him that would get him in trouble.
