Last night, when I was dreaming(ofc 
) I did an RC. I don´t remember why, but I did have six fingers. In the dream, I got lucid. I started rubbing my hands and spinning around. But I don´t think I got lucid for real. The dream did not start to fade away when I did the RC or anything, and I´m also having trouble remembering the dream.
But is it a progress?
If you realized that you are in a dream and that you are dreaming then it was lucid dream, but it looks like it was just a low lucidity lucid dream… Just keep going you are definitely making a progress…
Thanks!
Of course it is a progress. Even though you think it was a FLD, it is still a progress 
If you want to know if it was a LD or a FLD, you should ask yourself if you were actually thinking, that you’re dreaming. In a LD, you do that; in a FLD, you act like lucid, but you don’t realise that you’re in fact dreaming. I can’t say what you thougt during the dream, but you should know, that the first few LD’s are often blurry and may be confused with FLD’s.
That sure is a good step, eventhough loosing lucidness so quickly may feel like a dissapointment. Next step would be learning to stabalize the dream and raise your awareness after you become lucid. Good luck.
