Fallen Fog

Zaylia has lived in LA her whole life. Then, one day she wakes up to dense fog everywhere. The fog never goes away and it never becomes day. Turns out she is in coma. She has to survive a week in the "fog" world to get out of the coma. If she dies in the fog world, she has to keep trying. She have 3 tries until she dies in real life. Will she make it? Or will they pull the plug before she even gets the chance to try?
