What does it mean to have persistent dreams about being raped? is it because of my past catching up to me or some non sense dream interpretation?

Dreams: Dreams may contain a lot of symbolism and imagery, and the plot does not necessarily have to have a literal interpretation or correspondence with your waking life. However, dreams are also where we work out painful situations -- such as traumatic events. In dreams, we can go deeper into our inner experiences. Please consider discussing this with a psychologist, since you say it's persistent.

It could be PTSD: Individuals who have experienced trauma may experience nightmares about the trauma as well as other symptoms. If you are a victim of past sexual trauma then it might be ptsd. Please discuss with a medical or mental health professional.
