Ok as I thought the options for going through I also thought through what each of the options would tell me about a person. Rather interesting, the number of people who picked going in their sleep. Here's roughly what it tells me, feel free to add, I'm no psychologist.
Taking a bullet --> You're a romantic, who would want to die in the most dramatic way possible, with your lover shedding tears over you while you say "it's... ok, you must be *gasp and cough up blood* strong and.... move on*dies*". You would want tragic violin music playing as you leave the world.
Die defending Singapore/Family --> You're a person of duty who has a strong desire to protect what's important to you. Propriety is very important to you and you can sometimes have an overacute sense of righteousness. You may also be overbearing in imposing your method of doing things. You are a highly responsible person.
Getting killed in a road accident --> You always try to be different and would like to die spectacularly. You like sympathy and praise, even in death. You think nothing much of death, or of life.
Going in your sleep --> You are a highly pragmatic person. You are also rather peaceful and unlikely to rock the boat no matter what situation you're in. You are often the mediator helping to cool down a heated situtation. You think that the whole world should be friends. You are generally referred to as a nice guy or sweet girl.
Suicide --> You are bored of life and possibly depressed. You also are probably afraid of death or have unfinished business here or you'd be gone by now. Get help.
Martyr --> You're a devout man of God with great faith in your religion. You live your life governed by religious principles. You can occasionally go overboard with your beliefs by imposing them on others or being overly self-righteous.
Cardiac arrest at a party --> You're a practical joker who loves good humour. You like to entertain others and make them laugh, even if it is at your expense. Generally good-natured and likable, you even want your death to be something that's darkly humourous.
Killed in a world championship match --> You're a glory seeker and always aim to achieve the best you can be, no matter the cost. You want to spend your final moments at the pinnacle of achievement or at the height of your fame, in the public eye.
Just a little fun, don't take anything to heart. I have no training in psychology whatsoever.
