Has anyone experienced dreaming of a person whom you dont know of whatsoever and they tell you "you need to wake up."?

I had this dream a while back, a few years ago I think, where I was with a group of teens and we were trying to solve puzzles on a time limit, then while we were trying to go through a maze to solve one, a loud bell rang, like the one Big Ben has, and a bunch of distorted screams came from a bunch of people trapped against a wired fence. Then the moment we all got out of the maze, this girl( idk what her face looked like tho) who was a part of my group, ran up to me and grabbed me by my shoulders and said "You need to wake up, NOW." then, I tried to open my eyes but they wouldnt open, so I told her I cant, and cuz of that, she helped me lift up my eyelids to wake up, she said something to me before I fully woke up but I couldnt understand it. It was something like, "when you wake up, you need to-", the rest was cut off when my eyes started to open:P
Is that normal or is it just me???
