What happens when we die?

There was an interesting thread on Reddit about this asking people who had been declared technically 'dead' for a brief period of time (drug overdoses, resuscitated during surgery etc). Experiences were varied, but consistencies among many. They included:

- Nothing. Just blackness. Like you woke up from being asleep. No memory of anything whilst 'dead'. Common response.
- Moving towards a light or sense of 'good'/peaceful energy. Often accompanied by a voice saying "not your time yet". Common response.
- A sense of existing purely as energy, becoming one with the 'universe'. A few said these experiences confirmed to them that we are all effectively 'one' with the universe.
- Others said right before they 'came back', they were given the choice whether they wanted to or not.

We know how amazing and powerful the human mind is. This is clear through how vivid our dreams can be; creating worlds and scenarios that seem completely real. Therefor, some of the answers relating to anything but 'blackness' could just be the mind or consciousness technically still being active, temporarily, even though the heart has stopped. This may perhaps result in an experience similar to a dream.

A few other posters mentioned being near a river, or on a forest path. Creepiest response was a guy who's Father 'died' when younger. He apparently had been living a life of drugs, criminality etc. His Dad said he found himself in a dark basement type area being chased around by deformed characters. He went to hide in a corner, and as the screaming characters closed in, he found himself revived on the operating table. Turned his life around moving forward.
