Lost in a movie theater

I found myself walking around in the dark, and the movie had already started. I was searching for a place to sit, but it is dark and loud, so I am walking up and down the aisle to see if I can find an open seat. The faces of the people sitting watching the movie are dark and fuzzy. I began to wonder if I was with someone else, but I gave up looking for anyone, because it was too dark to make anyone out. As I get to the front row, I see an empty aisle seat, so I quickly sit down. I am relieved that I finally found a seat, but when I look at the movie, it is just flashing different colors and strange shapes on the screen. I look at the person next to me and I see that they have no facial features, just a blank face. I wake up confused and a little scared.
