Interesting. So part of your answer is [silent evidence](http://johnaugust.com/2007/silent-evidence) in the sense that there may be dreams where we continue dreaming after in-dream death, but we don't remember it?

<p>A lot of people had some experience with dying in their dreams.

Welcome to CogSci and thanks for the interesting question. Can you give a reference to your claim that death always means the end of a dream?

@Christiaan I am no scientist, so I can give no better reference than my personal experience and experience of my friends, unfortunately.

Well I've died in a dream and didn't wake up, and I'm an atheist. I just recognized on some level that it was a dream, didn't want to stop/wake, and experienced pretty close to nothingness for a few moments.

A lot of people had some experience with dying in their dreams. They all confirm they remember the whole story until the precise moment of death and it is the death itself what woke them up - not being nervous, scared or shocked (I remember myself dying peacefully in bed in one of my dreams, no fighting or falling involved).

It also quite a common plot of novels or movies: the main character dies and appears in some kind of "afterworld" - I have never met anyone with this experience, though.

Is it caused by the fact that our brain just does not know what happens next when it is all over?

Or is the moment of death such a "low-level" shock for our minds, that it just "reboots"?

When you dream you're in REM sleep (rapid eye movement). REM sleep is only slightly more "deep" than stage 1 of non-REM which means it's not that hard to wake you up in the first place.

Dying in a dream is a stressful event, which causes your brain to release adrenaline. You can't sleep and have an adrenaline rush at the same time so you wake up.

These dreams where you die and wake up are usually more memorable due to the fact that you wake up whereas most people don't remember 95% of their dreams.
