Why did I become lucid?

Iv been on a journey for the past year where iv meditated everyday....I'm now at 2 20min sessions a day.I haven't done alot towards lucid dreaming untill yesterday.I listened to a podcast with Robert waggoner for an hour.Was so good and interesting and made me exited to do one thing which he mentioned which was to call out in the lucid dream and ask 'show me something important.
By the time I went to sleep roughly 15 hours later due to a wake night shift I instantly had a lucid dream where I also did what I wanted....asked the question out loud.
Do you think the excitement and challenge of wanting to do something specific in a lucid dream improves your chances? I knew I was also on the verge of rem rebound....plus I did something new.....I slept facing the left which I never do....maybe the sleep position change or the excitement? Or even the fact that I spent an hour fixated on lucid dreaming?
Thanks =D

Yes, all of them : D

Even if changing the position didn't help, just you thinking about it may have helped. I'm not saying that it didn't help, because it may have had.
You set an intent. That is very important. I find that very helpful, since it gives you a purpose. I always get lucid easier when I have a goal and I'm excited about it.
Every time you think about having a LD, it helps. Thinking about it, drawing pictures of your plan, acting out your plan, writing your previous dreams to a dream journal... it's all great.

Happy dreams!

Yeah! It seems like all the factors really lined up. I am happy for you that you got an L D! Yay!

Thanks....always a wkd feeling when the work pays off even if it's only 1 or 2 times a month =D
