The Erratic dreams of StaySharp

I was in a building I identified as home in the dream, even though it's a totally unknown place. It was night, everything was pretty dark and the light in the room was pretty dim. There were some plants standing around and I think I remember seeing a bunch of jackets on the wall next to a door which was to my right, the room was pretty long and there was a small window ahead.

Something compelled me to do a RC so I pinched my nose and got lucid. Though at first I wanted to go through the door to my right I went for the window ahead of me with my gained lucidity, I prepared to jump out and did another RC to be sure I wasn't doing something stupid, even though I pinched my nose really hard I could feel my nose in reality being free and taking a deep breath. I tried to hover a bit and that worked, but with my low level lucidity a just fell down like a stone when I jumped. Some 10-15m on my way down I was looking upwards to the window I just jumped out, being calm and just taking notice of the fact I don't get the hang of flying right now. The impact was pretty hard (for the ground) but I didn't feel anything much so I got up and walked around a bit. I practiced some walljumps and after a minute or two I saw this dude standing on a roof. He noticed me as well and apparently thought I was some kind of cyborg or mechanical doll, created by a scientist who also created a similar being that once fought this dude. He was happy to see me it seems, because he wanted a good fight so he started attacking me, my lucidity goes down and I see myself roughing him up good with several interesting moves, partially in slow motion.
