Dreaming of getting old?

I recently posted about how I don't really dream at night. Apparently, I'm a liar. Because I had another dream two nights ago. The concerning thing is I think the dream was a premonition about aging. . . or maybe something else?

The gist of the dream was this: I was having trouble hearing out of my right ear. Of course, like most dreams, this one was very illogical and the setting kept changing. First I was in a doctor's office complaining of ear pain. The doctor kept telling me that I was not that old and that I was probably just imagining the symptom, comforting me, telling me that it would just subside on it's own.

Then I was transported to a vague situation where I was concerned about the noise level of the place. So, I wanted to wear ear-plugs or sound blockers in order to preserve my hearing. Now, I already do this in my waking life when working with loud machinery like saws, the snow blower, the mower, etc. I might get made fun of for doing this, but I am very conscious about protecting my ears.

Next, I was in a classroom, teaching. I kept asking my students questions and they wanted to answer. They were engaged. They were excitedly waving their hands in the air, wanting me to call on them. Yet, when I did, I couldn't hear them. I asked them to speak louder. I asked them to repeat what they said. I knew that I couldn't hear them because of my right ear. But the students didn't care. They were becoming very restless and upset that I couldn't hear them.

Finally, I was back in the doctor's office again, demanding she do an examination of my right ear. When she was finished, she confirmed that there was some serious hearing loss and asked me if I would like an implant or some sort of hearing device, which, obviously, I refused. I don't want a hearing aid! I'm not that old!
