@chaurey, the world spins around constant researches and findings. You and I are writing on this forums there are other genuises doing some sort of researches at this very moment. There were people declared dead by MDs and hence they're dead but they came back to lifee due to some unknown phenomenon. There are researchers who specially hunt for these kind of incidents. Now-a-days, doctors keep these kind of rare experiences in their journals as well. It could be career suicide to explicitly go public about these experiences but they know what's the real dril.  Their anecdotes shows what kind of experiences they felt after the death. Sum of all those incidents was what I've written in above. It's spiritual stuff, not an ordinary minds play.
Chaurey, ignorance is bliss but truth is a bigtime shocker. It just take little effort to expand the horizon of your knowledge. I take your comment as evidently natural response. no fuss :D
