Dream About Falling Into River Getting Surgery

We were on some school trip with my high school class but my elementary school teacher, walking through a forest, I fell into a river on the way and got my clothes wet, but I was fine, and we all went to a doctor, which I think was ORL but I'm not sure, I just know that in the dream I remembered having some of my own appointments at that doctor, and then they gave us some weird apron, and then I went first and they put me to sleep and made a cut on my neck with a scalpel and the last thing the dream was is me saying "I'm not asleep yet" and the doc "oh, you soon will don't worry". When I woke up, I still felt a warm spot on my neck, as if they really cut there. I feel a little uncomfortable, in the dream I was slightly anxious, but otherwise it wasn't too scary.
