Hm...I've had a few. Once I was beating some guy up with a gigantic wooden replica of an old Thunderbird car (it was life-sized), and I realized I must be dreaming. Then the dream started to fade out, and I thought, wait! I'm lucid, so this dream doesn't have to end here! I can do whatever I want now! Then I felt a sudden urge for popcorn, so I went and microwaved some...and then woke up. That was about it...

And there's a few others I've posted in the past, but I'm too lazy to find them. Something about blue owls and lightsabers in one of them...I'll see if it's in my dream journal in a sec.
