After practicing WILD for 4 days, I may have become lucid in a dream. I woke up almost instantly after but I heard this is common for beginners. The reason I'm not sure if it was true lucidity is that I didn't recognize any dreamsign or strange elements in my dream. One moment I was dreaming and then heard myself say "this is a dream" and then I woke up feeling my heart beat a lot faster.

Since I didn't recognize anything strange in the dream but just heard myself saying that, was this really lucidity?
