Sexual dreams

I've been having some really weird dreams since I walked in on my dad jacking off. Im only 13 and I allready have very sexual feelings. As soon as I'm allowed to go stay somewhere with boys I'm probably going to loose my v card. But back to the dreams. I've been dreaming that me, my dad, and this other girl(no clue who she is). Are having a three some together in a hotel while my mom is at a makeup event. All I know is he was having intercourse with her and she was sticking a cucumber up mine. I do masterbate but I don't stick things up in there. I don't use tampons. But then it turned around and he was having intercourse with me and I was supposed to be cucumber her. But then he bangs me like nobody's business and I end up reaching climax and having a orgasm. It all felt so real. I'm confused as to why I'm dreaming this. Any ideas? Please upvote.
