Yungen

This was in one of the shorter REM periods, so it wasn't very long.

I was standing in front of my school with one of my best friends when I realised that I was dreaming.
"Oh...My...God," I say to him, "IT'S A DREAM!!!!!!!!"
He disappears and I think 'Ok, I've got to keep this lucidity, I can't loose it. Do something special!'
I decide to fly, but not upwards, as I heard that I gets people out of lucidity, so I just fly about 4 feet off the ground but crash back down, my hands grazing on the pavement, I struggle to contain my excitement. I bump in and out of the air until the end of the driveway, where I fly to 20 feet in the air. The dream ends, or I forgot the rest.

I could have set the school on fire
But still, it was one of the longest times I've been lucid
