Dreaming of a Narco-Doctor, Police Cars, and a Mysterious Dungeon

I dreamt I was chatting with a doctor in a hospital, but the doctor was a drug dealer. I seemed to be very familiar with him. The hospital was closed at the time, and he was proudly telling us his history of drug dealing. I wasn't really interested in listening, just keeping up with "uh-huh," "yeah," "ah." My eyes were wandering around until I saw police cars. Several police cars suddenly parked at the entrance, right as the doctor was saying he had never been caught. So I asked him, "Then what are those police cars parked at the entrance?" Then our whole group fled in panic. Then the whole thing started over again. The doctor again, the police cars again. Then, fleeing to the back mountain, I saw a child. The child was injured. He said he wanted to play on a phone and asked me to get it for him. So I went back to the hospital to get his phone and some povidone-iodine to disinfect his wound. The little boy, in broken sentences, spilled a lot of gossip about the doctor, gossip about a massive pit, and gossip about a bunch of old folks. Then the whole thing started over yet again. The doctor, the police cars. I escaped through the back window and swiped a rope along the way. Then I walked to the hospital entrance, pretending I had just arrived, and ran into a group of old folks. They anxiously told me that a child had fallen into a deep pit and hadn't come out, but the pit was very deep and no one dared to go down. So I went to another building, swiped a flashlight, and went down the deep pit. Down there, I saw a dungeon, and deep inside the dungeon, I saw the unconscious child. I had the old folks pull the child up first, and then I ran into a cleanly dressed little boy. The little boy told me there was a sewer next to the dungeon where strange noises kept coming from, and he wanted me to go check it out. So I asked him to lead the way. On the way there, I saw a corpse in one of the dungeon cells. I quickly covered the little boy's eyes, told him to go ahead and that I'd be right there, and then I searched the corpse and found a gun. Then I returned to the little boy with the gun. The little boy told me this was the place, then stepped back fearfully, telling me to be careful. But on the way over, I had been thinking: does this little boy take me for a fool? What kind of little boy is all alone in a dungeon yet dressed so cleanly? Not only was he unafraid, but he was also exploring everywhere. The path to the sewer was incredibly complex—how did he remember it? He didn't actually react much when he saw the corpse, either. And as soon as he saw me, he asked for help with a very clear purpose, and so on. So I turned around and shot the little boy. Then I saw that he didn't die; instead, many dark shadows appeared around him. I turned my head and bolted into the sewer, locked the door, and kept running. I even heard the little boy asking me how I found out. I thought to myself, only an idiot wouldn't have figured it out, okay? Then, after wandering around, I ended up back in the dungeon, and then I saw a mirror. While looking in the mirror, I suddenly realized I was missing a canine tooth. Then I found that my canine had fallen out at some unknown point, and it seemed I had swallowed it. A new little tooth had grown in the empty space. Then I touched my teeth with my hand, and two of them fell out the moment I touched them. I was both scared and curious. I started pulling my teeth out one by one; they would fall out with just a casual pull. And for some reason, a whole bunch of extra teeth had inexplicably appeared in my mouth. Those teeth didn't look human either—some were long and flat, some were long and sharp, and all of them were very ugly and irregular. So I pulled them out one by one. I didn't feel any pain, nor did I bleed much. But when I saw that I only had a few teeth left in my mouth, I couldn't help but break down. I was truly having a breakdown (because in reality, I had just gotten my braces off after wearing them for 3 years). And then I woke up, completely devastated.
