For a perspective on dying:
Enter the Void. Watch it.
For a perspective on death: I had a major surgery and was put under anesthesia for 6 hours. I remember falling asleep, and it was hard to wake back up, but the space of time between sleep and becoming aware of my existence was instantaneous from my point of view. I didn't know how long I was out, couldn't even make a guess.
There was not even a void filling the space of time, no perceptible hole in time at all, it was like someone stitched the moment of falling asleep to the moment of waking up. If someone had stitched that moment to the death of the universe and end of time, I wouldn't even know the difference. That space of invisible time between going under and coming out is the only way to describe death.
