I'm a beginner lucid dreamer- in fact, I had my first "true" lucid last night. Anyway, this is how it started:
I had some dream (I forgot what it was) and then I woke up. I told myself to continue on with that dream when I go back asleep, but then realize it's a dream, and hopefully start a lucid. Well, I got back into the dream but I didn't know I was dreaming; I thought the dream was actually reality ( I was in a Buddhist temple for some reason). Within that dream I thought to myself, "Hey, try falling asleep and maybe it'll start a lucid," keeping in mind I had no idea I was dreaming. And then I instantly found myself in my room, and I was lucid.

I went outside and there was this really stupid looking city, but I flew around. I tried to fly into outer space, but I was going too slow. For some reason I wanted to wake up, and I did, but only in the Buddhist temple. That time I knew I was dreaming because I didn't wake up in my bed, so I told myself to wake up again. For some reason I couldn't wake up; I told myself many times to get up but I just couldn't. I thought I was going to be stuck in my dream. I eventually woke up in the middle of the night, really frightened. I was afraid to go back asleep, but now that I reflect back on this experience, it doesn't seem that bad.

So, I'm just wondering- why did my lucid start after falling asleep within another dream?

and, why when I tried to wake up I was in the Buddhist temple? Pretty weird.
