I called it my first LD, but I've been passively LDing without even knowing it was a LD, and this dream, well I remember it clearly.

Okay, so I went to bed with the thought that I'll fly in a lucid dream. I found myself in the seashore, along with other DCs. I didn't see any dream signs, but I turned lucid anyways . At that, I screamed "Oh hey I'm having a lucid dream!" I looked for the nearest person I could see. I saw a person, which looked like me, no, it was me! I said, "Hey you're dreaming!" That other me got annoyed and was like "Yeah right!" (That'll be my respones when someone will say that to me btw) I walked up to another DC and asked if he could punch me. I heard that if you believe it will happen, so I hoped he'll really punch me. But he just shrugged away (that was disappointing -_-).
The next thing I did was, "Since this is a LD, I should probably fly!" So I jumped, I thought hard to not hit the ground, and voila! I didn't technically fly, but I floated. I stayed on the air for about 10 seconds, and when I hit the ground, I lost lucidity.
