This could also indicate feelings of insecurity or fear of being judged by others. The appearance of your biological mother and her abusive behavior may represent unresolved issues or trauma from your past. The lack of intervention from others, such as not calling the police, may suggest feelings of isolation or helplessness. The physical injuries inflicted by your mother may symbolize emotional pain or trauma. Overall, this dream may be a reflection of past experiences and current feelings of vulnerability and betrayal in your relationships.
