You wake up on the middle of a huge grass field. You see only nature around you, no signs of present human life. You have no items with you except clothes. You see the mountains and trees in the distance as well as animals walking around. You don't know where you are wonder how did you end up here. You keep searching for signs of present human life but it seems you're all alone in this mysterious place, and it even feels different from Earth, although you don't know where are you. How will you survive? How will you get stronger? Will you return?
