Lucidity Achieved Again!

Yeah, Lucidity is something that happens to me very rarely. But last night was an exception. I was dreaming, and all of a sudden. I realized that I was! It was exciting, I could control things, I changed the scene a few times, I even killed someone. (don't ask, something I've always wanted to do while lucid). But then, the weirdest thing happened. I was in the middle of changing something in the dream world, and suddenly everything got very bright, so bright that after about 10 seconds I couldn't see anything else. Then something jolted me, and everything returned to normal in the dream. About a minute later I was conscious that I was hearing things in the real world, it was so weird, because I was dreaming, but I could hear things in the real world, I could even feel the weight of my body in my bed. Then, after about 5 minutes of me trying to retain the dream state and make myself fall asleep again, the dream started to fade. In about another 30 seconds, the dream was gone and everything was black. Then I just opened my eyes. The dream was over.
