Dream meaning » yelling
To dream that you or someone is yelling represents repressed anger that needs to be expressed. If you are yelling and no one hears, then it suggests that you are being overlooked in some waking situation.
You feel that your voice does not matter or that your opinion does not count.
In particular, hearing demonic yelling in your dream means there is something you thought you have left in the past that is still haunting you.
