The sense in dreams that you can’t hear or becoming deaf is the sense of the need for self-protection. This sense often occurs when one may have been violated or hurt in some way and had the experience amplified by social withdrawal.
Also, being deaf in dreams can have direct meaning or little importance outside of a past life or surreal moment. Sometimes, individuals have these kinds of thoughts as part of their conscience to deal with issues that may be difficult to express and uncover.
Often times, when dreams of being deaf occur, so does the unconscious mind’s explanation for it. It could be seen as a defense mechanism because the dreamer does not want to be caught off guard in a difficult or hectic situation. As well, it is unclear when a lack of sound enters the dream it is often accompanied by uneasy and distrustful feelings.
Being deaf in a dream can indicate that you are withdrawing from life and shutting people out. When experiencing deafness in your dreams it could also show your defense mechanism coming out because you are once again faced with an overwhelming event or situation that you do not want to face head on. Where sound is lacking in your dreams, they often carry with them feeling of unease and distrustfulness.
