Dream of screaming, woke up, doors, elephants, friends, kids, person, punched

In my dream I am observing myself at from a third person view. During my spectating I digress then progress as I go from being an elderly man in the future slowly trekking through my grand estate that is flooded with advanced technology. Next I turn into middle aged me running the chicago marathon. Thirdly I am in my early to mid 20’s and screaming and shouting as it appears I made some sort of discovery, then going out to celebrate at a party with many many friends and crazy college kids. Then it goes to infant me who is crawling at a brisk pace with a black nothingness background. Finally I see myself as a high school student and as I see myself walking away from school, I become no longer a spectator but a participant in the dream. I keep walking but now am headed to school. On my way there I am confronted by a man dressed in all black and smells so bad you can see it and he tries to rob me, but I fend him off and kill him. All of a sudden I am in a full out sprint towards school, and when I get there everybody is in the cafeteria yelling and crying. In attempt to get inside I discover that the doors are locked and I go to investigate why so. During my search I feel rumbling beneath my feet as a diverse herd of both rhinoceros and elephants stampede over the west field. As soon as I feel this I make a reroute for the herd that steers them away from campus except for one rhino and one elephant. After this scare there is another, as a bunch of angry assassins come towards our school. Headed straight for the cafeteria I think about going in but instead run to the schools medieval arsenal of bows, arrows, swords, and throwing knives. I grab as much as I and my recently obtained backpack, and head to the roof of the dining hall. I try to pick them off one by one at first with the arrows lighting some on fire and some not, but there are still twenty left as the cross over the road to the dining hall patio area. After doing so I grab my backpack and jump into a tree off the roof shooting four more guys with my green arrows. Then I create a mist of throwing knives as they begin to shoot at me. The knives got six more. With ten left I scampered out of the tree with five arrows penetrating my flesh from all over. I sprint to the rhino and elephant who are chilling near the basketball court to recover and get a drink of water. After doing so I go back to find the ten assassins had broken into the dining hall and had killed five teachers and holding everyone else hostage. I snuck in and acted as a student knowing they couldn’t have recognized me since I wasn’t wearing the hood or mask anymore. As I sat there pretending to share the fear and emotions of every other student, I selectively told people things were going to be alright and told a group of friends to go to a specific table towards the back corner. Then the assassins begin to threaten and attack students and teachers alike so I attempted to defend myself and others. In doing so I got shot two more times but took down six more guys. There was still four left. The four most deadly. Then there were sirens in the distant background, but it made the whole dining hall flash blue and red a couple times. Following this I realized the body count the assassins had totaled and instead of defending I attacked first. Surprised by my ability to dodge their arrows and attacks I punched one and kicked another. After this they all four focused on me as student after student escaped. During this confusion one of the assassins shot a student trying to escape and the twenty remaining stood still--frozen. Seeing it was a friend, I became angry, really really really angry. It felt like I was exploding with fire and then I started moving really fast. I defended against three more. Yet the anger didn’t subside and as I finally knocked the last guy onto the ground I stood calmed by the victory. With my anger subsided I stopped and then went over to the twenty remaining people who seemed to be heavily populated with attractive females and I carried them one by one out of the dining hall to safety. Afterwards, I avoided the cops and then rode away on a T-Rex with the rhino and elephant closely following carrying the girls to safety. Then I appeared upstairs in my house but it was black and the only thing I could move towards was the set of stairs that looked like they had no bottom. To satisfy my curiosity I jumped and then there was an explosion of white light and I woke up.
