Your parents are wealthy and you're their darling little girl. If you wanted something you got it, no matter how outrageous. There are entire stables full of your ponies, servants hired and fired on your whim just by mentioning your feelings on them. Your papa and mama love you, so when you demand to see under the sea, they oblige. They book a room on a tourist submarine, a strangely advanced piece of technology. The cost is prohibitive for most but your father just laughs off any concerns, paying it with no hesitation as long as it's for you. It's so fun! There were even dolphins! But something goes wrong. You're safe in your room, playing with your dolls, when the deck depressurizes. The rooms are sealed separately as a redundancy measure, so even though it kills everyone in the deck instantly, you're left alive. By yourself. At the bottom of the ocean. Finding your parent's bodies almost destroys you, but you hold on to hope. A week goes by and you start to run out of food, your stomach making painful noises that it never has before. You don't understand why this is happening to you. It doesn't make any sense. You're a good girl. As the feelings of hunger and thirst become too much, you curl up with your decaying parent's corpses, wishing you'd wake up from this nightmare. Trigger.
