8th and longest lucid yet!

Well, I have had a dry spell for a while until this morning. I had a very long lucid and it was just amazing! I don't know how I became lucid in the dream but I remember being in a fight with a butchers knife in the beginning. I was in battle with this entity and we were in a small, dark house. I was trying to fall asleep and I sensed an evil presence. I remember having trouble fighting him off with the butcher's knife or similar knife. I did a really fast 360 to gain momentum and I used that to take the knife and give the evil monster a little gift . I spun and stuck it right into his jugular and I almost decapitated him but I didn't go all the way through his neck. Only most of it and I looked at the evil monster as he dropped to his knees and was gagging. I felt so relieved and walked back to the room I was in. It is a really small room and rectangular in shape. I remember seeing another evil entity try to get into my room and I stopped it somehow. Usually after something like this I would wake up but to my surprise I was still in the dream. I walked outside to a dead end to the left of the place I just left. I instantly knew I was dreaming for some reason and just sat there for a minute trying to fight the urge to fall asleep. I remember my vision becoming blurry and I felt drowsy and dizzy and I had to put a great amount of effort not to fall asleep. I might have woken up or ended up in another dream and would have lost my chance for lucidity. I dropped onto the ground on my chest and started trying to move around. I instantly lost the urge to fall asleep and just to be safe I screamed out Clarify and Stabilize which I don't think helped that much but I did anyways. I remember my friend coming to me and saying he became lucid too. I remember going back into the house and pointing my finger at a small gnat. I tried to control it but I could barely do it. I moved my finger down and it didn't move. I moved my finger up and it moved towards me and down again and it moved away. I got bored of doing that and went outside. I ended up on a highway and I remember trying a lot of things but I don't remember what. I remember running and wanting to run faster and gaining a huge boost in speed. In the end of my dream I tried flying which ended the lucid dream and I woke up.. I'm still quite happy about my dream which lasted about 20-30 minutes.
