Last night was my first experience in a few years that resembled lucidity, and it was definitely my most confusing

Basically, I was dreaming normally, non-lucidly, when I had a FA. I sat up in bed for a minute or so and was talking to my (DC) brother when I decided to do a reality check. I found that my left hand had 6 fingers... but I don't think it sunk in.

After the reality check failed, instead of trying to change the scene or get up and move around, I decided to throw myself back into bed and go to sleep. I entered the "dream" within the dream, which was the same environment I was in before I had the FA, and was sort of lucid, but I still thought of the dream characters as real people and was showing them the stuff I could do while "lucid". I didn't really feel like I had much conscious control the whole time though.

I guess the dream logic was that if the RC fails, I would go back to bed and immediately get a LD My best guess is that it was some sort of device that my mind was using to try to trick me out of staying lucid. Has anyone else had similar experiences?
