I was searching for the exact quote but couldn't find it at the time of posting!
Thanks! 
...and this is coming from an Agnatheist ... but this is my feeling....and it's kind of winding to describe but whatever.
So you know when you're involved in something stressful, like a car accident or something where when you look back at it, the event goes on FOREVER. A 3 second event, in your mind, lasts for minutes. You can remember every detail of the window breaking, the tires screeching...and time gets back to "normal" once the car stops spinning or the accident is over.
Well to me, the "eternity" of death is that last moment of life, the last miliseconds of life. And, like the 2 second car accident that lasts for 4 minutes in your mind, that last millisecond is stretched out forever, because there's no "event" to end it. I mean, death happens but...I dont' know. It sounds very metaphysical for someone who has absolutely no belief in ghosts or life after death or anything....but I think that milisecond, the last thought in our head, is our "eternity", and that the idea of heaven and hell is really that last thought you have, the realization of the type of life you lead, the type of person you were, the goodness or evil you did for or towards other.
Hell isn't just other people. Hell is us. Hell is our deepest realization of how we slighted others in our life, and the inability to ever do anything about it, to never be able to right those wrongs, to say "i'm sorry." To take it back.
Heaven is the absence of those feelings.
I know that many religions see hell or damnation as the absence of God, the absence of light. I see it backwards.
I see Hell as the ultimate, never-ending guilt of how poorly we treated others. And the inability to ever do anything about it. Eternal regret without any resolution.
I see Heaven as the absence of those feelings. Heaven, basically, is that millisecond ending. Heaven is nothingness.
Now, do I sit and think about these thoughts and base my life on them? No. But they're the thoughts my husband and my friends have after we've had a few beers and maybe passed a J around the table and get into ridiculous nothingness discussions.
Get me REALLY drunk and I'll tell you my thoughts that the God = the brain = the universe, and how we're all part of something infinitely bigger and something infinitely smaller and that us trying to describe the universe is like a mitochondria in my cell trying to describe the mailbox outside my house.
But I need *really* good reefer for *that* conversation 
...is Paul Simon's answer (see video below).
However, the part of Paul's lyrics that I like best is at the end of the song:
And you feel like swimming in an ocean of love, and the current is strong.
But all that remains when you try to explain is a fragment of song...
Lord is it, Be Bop A Lu La or Ooh Poppa Do
I have a lot of music and lyrics occupying space in my brain, accumulated from all stages of my life. I expect that the last breath I exhale will carry with it the line of some long remembered song. Among the songs I recall are many that have helped me form my convictions about life and about death. One I sing quite often as I walk around the fields with the dogs is a variant of the song "Bristlecone Pine" written by Hugh Priestwood. It's a variant because I have modified the lyrics to match my thoughts on the 'afterlife'. (My lyrical modifications are italicized.)
Way up in the mountains, on a high timber line,
There's a twisted old tree called the bristlecone pine.
The wind there is bitter, it cuts like a knife
And keeps that tree holding on for dear life.
Hold on it does, standing its ground,
Holding as empires rise and fall down.
When the Pharaohs were gilding their coffins with gold
The tree was already two thousand years old.
From what I have learned I confirm for myself,
When I die I won't be anywhere else.
So when my time is over it would suit me just fine
To be placed at the foot of a bristlecone pine.
Then as I slowly return to the earth
What little this body of mine might be worth
Would soon start to nourish the roots of that tree
And it could partake of the substance of me.
And who knows as the centuries turn
Some part of me might continue to burn,
As long as the sun does continue to shine
Down on the limbs of the bristlecone pine.
From what I have learned I confirm for myself,
When I die I won't be anywhere else.
So when my race has been run I'd think it sublime,
To rest at the foot of a bristlecone pine.
Way up in the mountains, on a high timber line,
There's a twisted old tree called the bristlecone pine.
Here's a video of Michael Johnson singing the song as written. The Paul Simon video follows - on a lighter note.
Thanks for asking the question, hrmjustin.
If all times exist simultaneously, then you kind of live forever.
Huh?
Seriously, though...I believe that, until the Second Coming, it's soul sleep for everyone who dies.
