I'm sure the experience was just like fainting.

One moment you're [here] and the next you're [there] with zero perception of time or any other conscious experience in between. Why should one expect any other outcome when your brain is the thing that makes memories and provides the sensation of consciousness?

Of course... the afterlife-believers can easily say "well he didn't _actually_ die yet - and if he did, he would have had [insert my afterlife experience] and he wouldn't be back to talk about it".
