He everybody.
I’m a french boy so please apologize my english 
This morning after doing a verry beautifull lucid dream I was thinking about one important thing… Is the lucid dream a real conscient dream experience, or is it a dream of a lucid dream.
I mean that we may dream about doing a lucid dream, and we don’t really have control of this dream.
Please light my fire
Ah well, this is the number-one-argument of LD deniers and detractors I think. 
I don’t see a way to prove them wrong, but everybody who has had a LD knows that it’s not just dreaming about being lucid. It’s this feeling, this knowledge you get when you’re lucid. It’s really hard to describe, but LD’s are real. 
Also, usually dreaming of being lucid is classified as a FLD.
That happens very often to me, but I know when I’m in a real LD.
You just feel it.
As Leijona pointed out, a dream, where you are doing lucid dreaming stuff, but don’t consciously realise that this is a dream, is called a FLD.
A real lucid dream is a dream where you realise that you’re in fact dreaming. You may have no control of the dream, the lucidity level may be low, but as long as you have that thought in your head, it’s a lucid dream.
It’s hard to prove that our conscious mind controls our actions during a lucid dream, it may be as well our subconscious. But I would agree with GDra, you will simply feel that you’re lucid. You feel that you’re really there. This is one big difference between a FLD and a LD.
It is normally agreed that lucid dreaming exists, as proven by the works of S. LaBerge. And simple statements like: “You thought that you were dreaming, just because your consciousness made you think that” does not disprove the whole theory of lucid dreaming.
Although lucid dreaming is proven, it’s not completely established. It would be nice if some group of scientists scanned a person’s brain while he was dreaming consciously, and when he was not. Then, comparing the results, they should eventually prove or disprove the theory. During ND’s or FLD’s the conscious part of the brain should be inactive, while during a LD, it should be powered on.
The thing is that we don’t control the dream, at least not the whole dream but just the part of the dream that we are focused on…
For instance, you are in a dream and there are hundreds of elements and details and things that are happening and you saw something specific and you decided that you will change that. for example you see the grass and it’s red but you decided to color it in green, so that part of the dream you controlled, everything else was controlled/created by our subconscious…
Well, if you don’t think that your personality in dreams is fake (I mean, you don’t think that you dream your thoughts and emotions as you dream outside world), you won’t be so unsure about you were really lucid. Actually it would be obvious that you were conscious.
