Is one aware that one has died after one dies?

According to what religion? They all have different beliefs.

I can exactly report that as the heart stops awareness ceases. It is a very strange sensation to be having a conversation while lying on a hospital bed and instantly (to my perception) be flat on my back, wired up and a concerned cardiac technician leaning in very close

Ecclesiastes 9:5,6 teaches that the dead know nothing and have no knowledge.

(Ecclesiastes 9:5-6) "For the living are conscious that they will die; but as for the dead, they are conscious of nothing at all, neither do they anymore have wages, because the remembrance of them has been forgotten. 6 Also, their love and their hate and their jealousy have already perished, and they have no portion anymore to time indefinite in anything that has to be done under the sun."

But in the Bible the hope of a great resurrection when Christ presence returns will bring back to life both good and bad (John 5:28,29) this is a future prophesy.

I don't think so. The sense of "self" just isn't there. Perhaps earth bound spirits are those that couldn't give up their ego, either through being self centered or something similar.

One who is dead is aware of nothing.

Do you remember what it was like to be a blastocyst at the moment of conception?

No, when one dies one is dead and unaware of everything that one was aware of when one was alive..

One is dead. One is as self aware as a rock is.

The bible says the dead are aware of nothing, unless you are one of of the chosen ones that goes to heaven. The bible also says there will be a resurrection of the dead in the new system of things.

No. Consciousness ceases with the death of the brain.

Even if you believe the bible, it tells us 'the dead are conscious of nothing!

Nope.
