Not at all. What happens is you descended gently into the water, and the cabin doors open. The most beautiful merpeople you have ever seen, male and female, swim in, to the strains of "Stairway to Heaven", thankfully without the lyrics. Water, oxygen, it doesn't matter, living in breathing in nectar. You don't know whether you are in heaven or hell, it doesn't matter. You don't know why you waited so long before you bought that battery, as a merperson gently takes off your rubber underpants, and transport you gently out of first class into the fragrant waters beyond the exit doors. Thousands more await you outside, everyone is smiling and talking the same language.
Alternatively, there is nothing.
