I'm not sure what you mean was it about another dream state? As for a bit of clarification- the sex thing happened by myself, my roommate wasn't there. What I perceived when it happened: I was in my room on my bed lying down, naked (although I actually wasn't) and I felt like I could move. As for the girl, I don't know who she was, but I think she was in my "normal" dream and then I transplanted to her my room once my eyes opened.
