Last night I had my second lucid dream, but it was about 3 months after my first. I'm not complaining, my first lucid dream took 3 years of trying, I'd just like a couple answers on what happened.

So, it was a DILD, I was inside a Coldplay music video and I told some little girl that she was in a dream, then I realised that I was the dreamer. I told myself to calm down and ended up in my bed anyway. I tried to synthesise a new dreamscape so I could get back into a dream, but it didn't work. I didn't try moving, I thought that I might as well go straight back to sleep. I did pretty quick after, but I'm just wondering why I was kicked out the dream, I didn't jump around and send my heart rate skyrocketing, and I didn't breathe too fast either, I just wanna know why I woke up.

Thanks a lot guys!
