...did I do it?

Last night, I was randomly researching Lucid Dreams and Idoser. I didn't go too into detail, only to a couple of sites. About a year ago, I was very interested in Lucid Dreaming and spent a lot of time researching it, so I know a fair amount anyway.

When I was dreaming last night, I think I realized it was a dream. My normally Miss Manners grandmother was acting completely rude in the dream and I realized that this was impossible. I remember thinking to myself in the dream that I was in fact dreaming. As soon as this happened, I began to feel "less involved" in what was happening around me in the dream. It was almost as if I became transparent and felt very wavy and the dream was less intense and deep. I remember thinking that I was able to go somewhere or do something, but I had no interest in leaving the situation. What I recall of the dream ends shortly after that.

Now, for my questions. Has anyone else experienced this sort of removed, transparent feeling in their dreams? I have heard some people say that when they realize that they are dreaming, they become very deeply involved, quite the opposite of what happened to me. Is it possible that I was only dreaming about lucid dreaming? That may not make any sense, but since I had been researching it right before I went to bed, I may have just had it on my mind...? I hope my questions make sense. It's so hard to describe these kinds of things!

Thanks in advance for any input.
