Sleep event

Notes: I have been having lucid dreams very frequently since eating shit on bike this summer and concussing myself. These almost always occur just after falling asleep and usually end with the sensation of choking, resulting in waking up. I also almost always drool during these events. --- I appeared, quite suddenly, in a long metallic looking hallway glowing with a strange red tint. I perceived that this was representative of some distant war fire. In reality, I had just sent my friend a Facebook message before suddenly falling asleep. Instead of focusing on the still empty hallway I thought about that for a minute, then turned my attention to my physical body, which felt numb. I could feel myself drooling. Realizing I was lucid dreaming, I decided to stop wasting my time focusing on external factors and focus on the dream. My first thought was to dream about fighting off a horde of baddies. A bunch of grunts wearing steel helmets and lamellar armor appeared. An axe appeared in my hand. I started to fight. At first, I could not move quickly. Something in my mind was holding me back from fully controlling the dream. I thought "no, move faster" repeatedly until eventually, my dream self could move full speed. My brain continued to try and derail my lucidity. At one point I conjured some fat dude in office attire to grab me and pull me away from the action. After thinking, very purposefully, "fuck off" a few times, he did so. Almost immediately after that, the part of my brain that wants to confound me conjured my dad and tried to turn my lucid dream into a nightmare. He was being attacked by several grunts, his hand reaching out to me from between a door crack. I knew my dream was going to have him killed. I threw my axe and stayed one grunt, the other disappeared. My dad lay bent over unnaturally over a couch, I could tell part of my brain was waiting for me to interpret his figure as dead. "Nope, he is fine," I thought. Dad sprung back up, totally untouched. At this point, I started to feel the choking sensation and knew I was not going to be able to remain asleep. I felt like I could not breathe. The dream swirled out of focus. I began to hear my physical body making a choking noise. I woke up and breathed. My pillow was covered in drool.
