I had my first LD when I was 7 (I'm 15 now) and it was the only one I've ever had. I didn't know what lucid dreams were back then either. I was at my day care in the living room, and all of the sudden, a garbage can appeared and out popped Frankenstein! . I immediatly knew this wasn't real and I became friends with him. Then I woke up. That is about the only dream I remember from my childhood.
