this is what i did in my first LD:

I am sitting in the grass, when suddenly a huge yellow bus comes over a hill and dissapears again. "damn" this must be a dream. I become lucid. I stand up and start to run. As I run my speed increases and increases until I'm flying like a bird.
I fly faster and faster till i can see a lake underneath me. "I want to jump in there" i think. Then i just let me fall down for a minute or two until i reach the water. i died and woke up.... sh*t
