Mirror of Rotting Teeth & Locked Door Meaning & Interpretation

"I was standing in front of a mirror in my bathroom. I looked at my teeth and noticed that they were turning yellow. I opened my mouth wider and saw that several of my teeth were badly rotten. They were dark brown and had small holes in them. I became scared and touched one of the teeth with my finger. Suddenly, the tooth became loose. I tried not to move, but another tooth started shaking. Then several teeth began to fall out one after another. I looked down and saw the rotten teeth lying in the sink. Some of them were broken, and others were covered in dark spots. I tried to call for help, but when I opened my mouth, I could not speak. I looked back at the mirror and saw that more of my teeth were becoming rotten. I ran to the bathroom door, but it would not open. I pulled the door again and again, but it stayed locked. Then I heard a tooth fall onto the floor behind me. I slowly turned around and saw a pile of rotten teeth on the floor. I woke up suddenly, feeling very scared, and checked my teeth with my tongue."
