Oh, and in addition to my explanation, I used the location and nose-plug RCs to get lucid, then I got this amazing feeling but I couldn't really move in the dream, I only stood there and saw the surroundings awkwardly start to change.. Until everything faded and I found myself falling somewhere I couldn't tell, then I had the FA and SP (or SP dream, since I remember kind of seeing parts of my room with my eyes closed!)

And just another detail I observed.. As soon as I became lucid, I started to hear some "shock" noises in my head, like there was something electric going wrong.. And after the environment changed, I started too mix images from what my eyes were seeing (the room's floor) and from my dreams.. Like my eyes were opening and closing really fast, but I couldn't feel it opening.
