Hmmm... that reminds me.

I haven't had a fully lucid dream yet, but one night, I was halfheartedly attempting WILD along with aid from a Lucid Dreaming mp3. Right as I started to lose consciousness (unintentionally), I immediately heard a loud growling from beside my bed, even with my noise-cancelling headphones on and my dog on the other side of the house.

It freaked me out, big time.
