So last night I had a dream where my friends and I were on a bus. We were going back to my house. As the bus passed the parking lot, I saw my friend sitting in my car, which I had used earlier in the dream. I realized I shouldn't be on this bus and that I need to get off now! I was supposed to drive him home along with my other friends. I got really scared that I would get them back on time. I put my hand into my jacket and pulled out my car keys. Looking at the other guys I said, "I locked the car, so how could Dave be in it?" I didn't think any more of it, I needed to get off this bus! I saw a stop coming up and thought I should get off on it. I couldn't make up my mind whether or not to get off. That's when I remembered about my keys and how my friend was in my locked car. "I'm must be dreaming", I said. I quickly spun around and looked at my friends on the bus, all of them were smiling at me. Then I woke up.

So I'm not sure if it is a true lucid dream. I woke up right as I realized it. Right before I went to sleep, I watched this link from another post about subniminal lucidity or something like that. I think it worked! I'll try it again tonight, maybe I'll have better results.
