This wasn't my nightmare, but my friend had this nightmare a couple months ago where he was in one of my school's hallways and everyone he knew from school was just standing there, and wouldn't respond if he talked to them, poked them, etc. He blinked, and when he opened his eyes everyone was on the floor, dead, except for someone standing at the end of the hallway. As he walked closer and closer, he tried to hide from the person. Then, when he finally got there, the person turned out to be himself.
