Tunnels

One day your walking peacefully in a meadow, when you fall straight down into a tunnel! You are a little bit injured but you can still walk because you landed on a soft mattress. You look around darkness surrounds you but there is still light coming from the top of the hole that you fell in. You get off the mattress and you walk into a puddle of water, it looks like your in some kind of sewer. You try to climb back up but it's no use. You then scream for help, hoping that someone hears you, but then you realize that you were walking alone in the meadow. No one was around when you were walking, you were by yourself in a big empty meadow, far from civilization. You scream for help one more time, but still, no one hears you. After screaming for help you decide to find another way out of this sewer. There are two different directions that you can go to, left or right?
