Fire and UFOs

I keep having a dream about being outside and watching the sky. The sky starts to turn really black, with thunder rumbling around. A gap appears in the clouds and then huge swathes of fire rip through the air, rushing towards me.

Another quite vivid dream last night - the sky went all sparkly, then a range of UFOs came slamming down into the earth, coming towards me - I manage to jump out of the way just in time.

Have you ever had any lucid dreams?
