Why I want to learn to lucid dream: It just seems really fun! If I can learn to be aware of my dreams, I can try to control it and do everything I couldn't do in real life ^_^
What I will do in my first lucid dream: I'll try to stay calm, and walk around for a bit. I'll just go with the dream and see what happens, maybe try to do something small like make a pencil appear. When I wake up, I'll write down everything I remember.
