Head for Portal 18
From Create Your Own Story
You close your eyes and let the sock-worm-thing snap you up in its jaws. What luck! It's teeth are just as soft as cardboard. Actually, eating you has caused this monster a good deal of pain, as your body is much harder and more durable than the monster's usual sock-based diet. As you find yourself tearing through the beast's esophagus, your last thoughts before tumbling through Portal 18 are a silent prayer that you haven't upset this strange Sock World's ecosystem by killing one of its predators.
After a flash of whitish-yellow light, you find yourself in a cave. You see shadows projected on the walls of the cave.
You turn toward the light source and head that way. Eventually, you find yourself in a utopian dimension of Pure Forms. You see amazing things and experience things too grand for the human mind. The process breaks you down, crushing your mortality. But then you ascend. Higher and higher, gaining enlightenment. You arrive at the gates of heaven and are given a mark. Then there is darkness. When you awake you find you are standing on a street in your hometown.
You walk down the street and buy a chocolate chip cookie ice-cream sandwich. Delicious!
