What does it mean if this happens in my dream?

Scream

To dream that you are screaming symbolizes anger and fear. You are expressing some powerful emotion which you have kept pent up inside. If you try to scream, but no sound comes out, then it indicates your sense of helplessness and frustration in some situation. No matter how hard you try to get someone's attention, they cannot hear you. The dream highlights your difficulty in communicating with this person. You need to immediately identify your fears or feelings and confront this situation in real life.�Alternatively, your inability to scream may be a form of REM paralysis.

To hear or dream that someone is screaming indicates that some friend or family member is in need of your help.
