This dream may represent feelings of powerlessness and vulnerability in your waking life. The old man could symbolize authority or a figure of authority in your life, and his actions of holding you down and raping you could reflect a sense of being overpowered or violated by this person. The fact that you couldn’t scream or move suggests a sense of being silenced or unable to defend yourself. This dream may be a manifestation of past trauma or current feelings of being controlled or taken advantage of. It could also be a reflection of fears or anxieties about losing control or being victimized in some way. It is important to address these feelings and seek support if needed. Consider talking to a therapist or trusted friend about any experiences or relationships that may be contributing to these emotions.
