This movie is based on the speculation that something dies because there is an invisible spirit of death that follows you around from the day you are born, and that it waits, waits, and waits, until you are sick or injured enough to die, and then enters your body. Because it gives it a super duper orgasm or something, I don't know.
Anyway, the point is, this spirit of death entering your body is what MAKES you die, and without that happening you would never die, no matter how old, sick, or injured you are.
It's sort of like the opposite of the belief that when you die something LEAVES your body.
A researcher realizes that if he can trap his Asphyx (everyone has their OWN) so it cannot enter his body, he will never die, and he does eventually manage to trap it in a circle of phosphorus light that it can't escape from.
As you might imagine, this movie doesn't end well.
It's truly terrifying.
Don't watch it if you don't want to have nightmares.

and they are appearing in plain sight, we must be in for a worldwide cataclysm of some sort soon.
