Questions (please read)

In the past year I was randomly getting dreams like once every couple months where I realized I was dreaming and could completely control what I did and my surroundings and could even bring people into my dreams and pretty much have them do what I wanted. I didn't know it as lucid dreaming. I just thought I had gotten lucky and it was really amazing. The last one I had didn't last for that long and right after it I was laying in bed kind of half asleep I was like halfdreaming of myself going to the computer and searching for ways to make this type of dreaming happen more often, the thought of a pill that induced this type of dreaming even went through my head I think. Anyways that thought brought me to hear where I learned it was called lucid dreaming, and I am absolutely intrigued to read all these methods to induce and prolong lucid dreams. Before I knew what lucid dreaming was I still had little methods to make them longer while I was in them. My question is, is it common to have such vivid lucid dreams just randomly, without any strategies or without practicing all these things I have been reading about? Because I had dreams where I could just have whoever I want in my dream and do whatever I want. Also, after reading what I have written so far, where do I go from here? What stage would you say I am at? The first? Any suggestions would be appreciated.

Thanks
