To dream of a hearing aid represents an inability to genuinely be listened to or understood. Difficulty getting ideas through. You or someone else that needs something done before they give their full attention. Alternatively, a hearing aid may represent a coping mechanism to help you stay informed or included as part of a group. A dependency you have that lets you keep informed.
Negatively, may represent a requirement or condition in order to listen to someone else. A bribe or condition that has to be met first. Something to make co-operation more palatable to you or someone else. A method of overriding stubbornness. It may also be a sign that people don’t want to do anything with you unless they can use you. may also mean you are too dependent on someone else to get information.
