Dream of coma, chased, building, died, hands, person, tooth

I dreamed that some people which made fun of me when I was at school walked passed me. I didn't say "hello" and they got upset. One of them told me that they want me to say "hello". This one person wanted me to come with them to a room which somehow felt familiar, but never was there before. I had a bag with me and after hesitating I left it next to the door and walked into the room where everyone else of my ex-class was sitting. I said "hello" and sat down. We started to talk to each other, at the beginning I was very shy and after some time I started to actually enjoy talking with them. And then I felt like my teeth in my mouth got bigger and I had difficulties to talk, I started to sound really funny. My teeth started to wobble and I didn't understand what was happening. I had the feeling they're going to fall out, so I left the room immediately. In the corridor I got on my knees and it started to hurt and my whole jaw was under pressure. I got scared, my teeth started to fall out into my hands and on the floor, I could feel them slipping out of my gums. As they fell out I was crying. I looked at the floor and stopped as I saw something shiny laying on the floor, it looked like a stone. I took up a tooth and the tooth was white, but like a shell, empty on the inside and as I looked again there were tiny little diamonds in my tooth. I picked up another tooth and the same there, all my teeth that had fallen out had little diamonds inside them. I was surprised and before I could feel happy about them, I heard a wasp swarm outside and saw them on a door with window. They wanted to get in. I grabbed all my teeth and diamonds off the floor and rushed into the room I was before with my ex-class mates. The class mates have already left and the wasps got through the door and looked for me. In the room I hid my teeth and my diamonds inside a wooden already damaged bench or chair. I ran out of the room as the wasps started to chase me. I had a short look back before I left the room and saw a weird looking wasp with something like a red horn on its head. It was the king wasp of the swarm. I left the building. The king wasp chased for the diamonds and my teeth and got trapped into the bench/chair. Outside of the building the other thousands of wasps started to bomb me (what? xD) and people around me. There was an army outside the building and some people I knew (but can't remember who it was). The army started to shoot the wasps and tried to bomb them back, but the wasps were indestructible. At the same time someone looked for the king wasp. This person eventually left the building as the wasps tried to protect themselves inside the house from the bombs of the army. Then the wasps started to bomb the bench/chair where my diamonds and teeth were hidden. And then a thought went through my head: To be able to stop the wasps, somehow the king would have to be killed. The only way to kill the king was to make him drink blood. I looked for a doctor and found one, he was right there in the middle of this happening. I told him that we need to catch the king and make him drink blood. I wanted to spend my own blood. But the doctor opened something that looked like a big fridge and there he took out some bags of blood. He said the blood was from the king wasp. I asked him how he came to that blood and then he took out a tray and there was the king wasp laying. Still alive, but it was in kind of a coma. The king was much bigger than before. I ripped the horn out of its head and held it in my hand. The horn still had kind of a vane or stream attached to its head which lead into his mouth. The whole thing looked like a funnel. It was meant for liquid. So I took the blood which was drawn of the king wasp own body and put it in the horn funnel so it would drink its own blood. As the blood was in its mouth and it swallowed it, the king wasp died and the same second the whole wasp swarm died and fell on the floor. I felt relief.
