I don't think it's nonsense at all. I think you need a body in order to be conscious- as a human being. So dead, without a body, we go offline, like a piece of software being taken out of a computer. But when our hardware gets upgraded, and our spirits again have a new body through which to express itself, we come back online, and to the individual, no time would have passed. I think the sleep metaphor is for the living, to help us understand something that happens in timelessness. If you were to die tonight, as a Christian, your eyes would close, and then immeadiately seem to open in your new body, at the rapture. Several years or decades may have passed, (by earth's reckoning).
It's nearly over, but have to say it was pretty even handed. Many viewpoints expressed.
At one point Walters talked to a jailed failed muslim terrorist.
She also speaks with a moderate Imam.
Besides the terrorist foaming about how everyone but muslims will burn forever in a fire "70 times greater than the hottest fire on Earth", both he and the Imam mentioned sex in the afterlife repeatedly.
What strikes me about Muslim views an afterlife is a description of a decadently hedonistic selfish eternity.
The Imam interviewed bascially said muslims when they enter paradise will all get to have orgies forever.
How evil and twisted.
