I'm not quite sure why some of my dreams resemble video games. I don't play video games. But this one definitely had a video game feel to it except for the feeling of actual horrible death.
There were different doors to choose from. I was in a team of people (who I didn't personally know). We picked a door and our goal was to get something (a prize of some sort?) without getting killed by obstacles. We entered the door and found ourselves in an underground tunnel-like place, a lot like tech's underground steam tunnel system--all dark and morbid. I accidentally flipped a switch.
Then we realized that to defeat the obstacles, we had to be experts on South American mythology. And since none of us knew any South American mythology, we struggled to open the door to get out of the game. That's when we began hearing buzzing approaching us from around a bend in the tunnels. Flying monsters apparently derived from South American mythology were coming after us. If we didn't open the door, we would all be toast. That was when I woke up.
