My Wapped Dreamscape

This dream happened in the morning on going back to sleep, this dream was very vivid:

I was in bed with a very good female friend of mine (we're close but not that close) and noticed I was on the right hand side of the bed with a story being red to me in the background ( I had "Weilding a Red Sword playing on the MP3 player).
On looking I found that she was completely naked while I as normal just had a pair of pants on. We start cuddling etc and she removes my pants, but before anything can happen she asks me to check what the title of the book is on the side table next to me, I roll over and though I don't see I book, I say "The Five Rings" (This is a book mentioned in the story I had on my MP3, at this point I become suspicious about the reality of everything and to test if it's a dream I ask her to switch on the side lamp, at this point I wake up.
