What is your personal nightmare way of dying ?

Eaten alive by, well pretty much anything. The last thought in your head is that you are nothing but meat. No.

I always have this fear of having a heart attack or anything that could happen to the heart.

the deaths i had in my nightmares...falling from high heights and car crashes

I would say drowning, but that's too obvious so I'll point out a death that I saw on a movie that haunts me to this day. In 28 weeks later, the sequel to 28 days later, a woman is strapped to a table because she is believed to hold the infamous virus that turns people into violent, aggressive, and fast zombies. Unfortunately, someone in the room with her has also contracted the virus but has actually succumbed to its effects. Seeing as the person is now violent, they proceed to attack and kill the woman strapped to the table. You would think that this is bad enough to be attacked while immobile but what's worse is how the final blow was delivered. The zombie plunged its fingers into her eyes and pushed while she struggled to break the straps. I would rather drown than die this way.

" Getting chopped up in many pieces, then cooked with celery. "

guillotine, having your head cut off and looking up if your brain and eyes were still working would suck.  It would probably be quick but still.

Thought about this one a little bit. Being tortured in any of those crazy medieval times ways would suck, but in particular, think about this:
 
Stripped naked and thrown into a cremation furnace, except that the fire isn't turned on high so that the flames directly touch you. You're just on top of a ridiculously hot metal bed, with no possible chance of escape, so your body will just blister and essentially cook itself from the inside out over a fairly significant period of time.

Anything slow and painful would be the worst. However, the thought of getting my head cut off and still being "alive" for those few second(s) after to maybe realize what is going on before dying would be the worst experience ever.

Getting put into a coffin and buried alive. My god being trapped that deep underground must suck ass.

" The worst, most frightening and terrible way to die IMO is to be stranded in the middle of the ocean and attacked by sharks..... my god how much it frightens me and makes me shiver.  you ? "

" Getting put into a coffin and buried alive. My god being trapped that deep underground must suck ass. "

Being locked into a really small space. Something the size of a tiny closet. Alone. With no hope to hold onto.

I honestly have a huge fear of deep water. I've had many bad experiences involving water and I don't swim. Just being left in the Ocean with nothing around would be mine. Even in games when you have to swim I get a little nervous. Fallout 3 really was bad for that with me.

Brazen Bull is a death by dehydration in a small dark claustrophobic area where you are cooked alive.  Unlike burning at the stake, a tube is connected from the bull to the outside so instead of suffocating and passing out you will instinctively prolong the conscious roasting of your body.  The tube is modified to convert the screams into the sound of a bellowing bull for the amusement of the audience.

same here. :\  "

Buried alive or drowning. Basically any situation where I know I will die, and I can do nothing to prevent it.

starving to death, and not being able to do anything about it

Falling off a giant cliff. I'm deathly afraid of heights.
 
Or even worse (to drop some emo stuff on you guys), to die without having some sort of significant impact on the people I care about. Basically, dying alone and having no one show up at my funeral.

When I was younger I had nightmares about sinking underwater with a ball and chain tied around my ankle.

global nuclear war
 
watching the wall of fire racing towards me and thinking oh how these fools have ended it all.

I agree. "

Probably having something crush me, like being in a room with the roof slowly coming down.

Being slowly burned alive.

Alone.
 
Otherwise I don't really have any fear of death.

worst: probably slowly bleeding to death
 
best: getting mauled by a bear while shooting with a bazooka full of swordfish. (my plan on going out)

This thread has made me afraid to go to sleep. Thanks a lot.

" Asphyxiation in any way. "

Death by Irony. 
 
That, or anything in the movie Seven.

Fucking bring it! Death you don't scare me!!!

Being forced at gunpoint to eat a mouthful of very live and very venomous centipedes.

Being eaten from the inside out by some sort of parasites, somehow becoming paralyzed from the neck down while stranded in the woods, being weighted down and tossed into water

Being chopped up piece by piece by a psyco serial killer; starting with the non vital parts.  
 
Any version of that will have to do.

" Alone.     ..... :( "

Zombie, has to be Zombie. 
 
Or desert Island, where all you have to eat is sand, and all you have to drink is piss.

drawning or choking of any kind

I cant swim so it would be drowning.

having my hands and feet tied to four different horses or cars and have them drive away in four different directions.

Drowning, or getting murdered horror movie style. 

Anything involving my balls and/or eyeballs.

Hmm. This is a good question. I think it would have to be being mistaken for  dead, having a funeral and what not being buried, then me waking up 6 feet underground still alive.. then dying from lack of oxygen. 

Drowning probably or being stabbed to death.
