You were running away from your abusive parents, as you couldn't take it anymore. Leaving behind that cruel life was the best thing that happened to you. You ran, as far as your feet could carry you with no too little clothes and no shoes on. You saw a near gas station, hoping to stop and have a breather before continuing - but evidently, you ended up passing out from dehydration and low food.

Ghost: "....you poor thing... don't worry we got you"
