I had a lucid dream last night. And just like this post, it was short.

I remember looking at my hands and seeing something strange. They were really elongated and had less fingers. Then I said "Gasp! I'm dreaming! I'd better do something before I--" I suddenly woke up "--wake up..."

One thing I noticed during those 3 seconds was that I didn't feel as hazy as I am in non-lucid dreams.
