Hovering

I had my first lucid dream like 3 hours ago!! So I had been dreaming a lot of things and suddenly I wake up. And I think to myself (I had not moved and my eyes were still closed) if I am quick enough I will go back dreaming and stay conscious at the same time. The next thing I know I am running in my street, past my house. But everything is very dark, like nightmare-ish. Then I suddenly fall to the ground and I think to myself "I am dreaming?" So (for the first time ever in my dreams) I do a reality check and look at my hands. I have like 7 fingers and some of them are really small. It is funny but that moment I was just 'relaxed' and I thought to myself "Alright do not get too excited here". It was still very dark and if I stayed there any longer I knew something bad was going to happen. So I think "I will just fly out of here", and so I do and I fly through the house next to me (superman-style) into the sky and BAM, I am somewhere else. I am hovering 50 feet above the ground and below me are many constructions and cranes. Everything was very detailed. So I look into the distance and as I gain altitude things just "pop up", like in some kind of video game. I do a reality check again and suddenly I have somekind of mission to complete. At this point I am not sure if i was still lucid, because I had to complete this mission and I did not think to myself that in real life this would not make much sense. So my question is: Can you be lucid but like play along in your dream? Because i think I did. So my mission was to infiltrate some large complex. I fly through the first wall and again, I do a reality check and still know I am dreaming. Some people from university and some people that I do not know are with me too and are helping me. Me and a girl are in a hallway and parts of the walls and ceiling were coming towards us and would crush us. But as I knew I was dreaming and could control things, I raised my hand and with somekind of force power stopped the walls from coming towards us. I take the girls hand and jump through the ceiling and run through several walls. Finally I am in the main office of the complex and (yeah it is stupid I know) the mission is accomplished. All of the people who helped me were there and because of this 'adventure' we all had become very close friends. We were all very sad because I knew my dream would come to an end soon and we would not remeber each other or what we had been going through. So as my lucidity is starting to weaken I quickly grab a pen and start writing the names of my new friends on the palm of my hand SO that as I woke up I knew who they were in real life and could visit them. I really hoped that it would work so that I could make contact from this dreamworld to the real world. Sadly, as I woke up nothing was written on my hand So yeah this was my first ever lucid dream. I think it was pretty cool and I think it lasted for about 15 minutes with a couple of Reality checks throughout the dream. Hopefully my dream was enjoyable to read
