First off, I understand your curiosity about your dream. I think it is a very natural, normal thing to wonder about what it all means and have some of the questions you do.

I don't think it's "sick" that you dreamt of this? I am also a CSA survivor and occasionally, have dreams that are related to my past and difficult for me to process or understand.

I would strongly encourage you to try and talk with your T about this matter. This is your therapy and if it is important to you, then share it with your T. You are paying him to help you, not the other way around.
