I have had lucid dreams before. But this is my first after being determined in having one

I had just touched Luke Perry's hand :S (I don't really fancy him irl). I then tried to count my fingers on that hand. But I couldn't because it felt like some fingers were stuck(in my sheats I was thinking). And I knew it was a dream. I then looked at Luke and knew that we were alone and I thought he looked cute. So I just jumped on him. We kissed and bla bla. The weird thing was that I jumped between being in my bed and with Luke. I ended up in my bed but could still feel him touching me. I tried to stop it and get back in the dream. But couldn't and woke up instead.

I sat up in the bed and saw a poodle of water started to emerge from under my bed. First I thought I had just spilled some water from my water bottle but the floor ended up being covered with severel cm of water. I then ran out in the kitchen where my dad was. He asked me in an angry tone what I had done. I was really confused.. bla bla.
I realized I was dreaming again way later on and then tried to fly. It was difficult to just lift from the floor so I jumped from a chair instead. I just hovered for a moment and fell on a carpet. It didn't hurt at all so I guess now I was more convinced that I was dreaming and ran out the door, and tried to fly again with more ease this time. But it felt more like jumping very high than flying. Cause I couldn't stay up there for long. And a bird almost flied into me :p heh
I woke up again but it was another false awakening. It bothered me so I then focused in waking up instead. I succeded but it was an effort and I woke up paralyzed for a few seconds and with a headache.

I have tried flying before in dreams. I can fly a bit but not for long then I fall down. Up and down, up and down. There's always a limit to how high I can get too.
This really annoys me cause I'm studying astronomy and I really want to explore the universe and leave this planet :p
Does anyone have any experience in doing so? Flying past the layers in the atmosphere and out into space?
I was thinking maybe to just focus on the moon or a star and try to fly towards it, instead of focusing on leaving the earth or something. That's at least what I will try to do next time I have a lucid dream
