Wow, congratulations! Yey.

You seem really excited...so I hate to bring this up...but just from what I've read it seems like you were watching HI. The smoke, forming shapes and scenes. That is DEFINITELY hypnogogic imagery. I think that's why you felt you needed to make a "body" ...you see...if you had moved from the HI into a lucid dream, there would have been no need for this.

I've been at this stage many times. It is exactly as you describe it, like changing channels on the TV. Just watching. That's HI. I think it's really awesome that you managed to get there. If you waited longer and allowed yourself to follow the HI into a true dreamscape...I think you would have experienced a real LD then. But instead...you fell asleep and probably had a dream then that wasn't lucid because you lost awareness at the HI stage.

You did get really far though, so congrats.
