what would happen to our conscience after our physical and sensory understanding of the world was removed?

If you study people that had the "death" experience and came back, they all say that their consciousness never stopped, even in people that were clinically dead for over 45 min then revived.
There is a book called "Proof of Heaven, a neurosurgeons journey into the afterlife". By Eben Alexander M.D. who was an athiest until he died and came back, now he believes in God. The only science we can have on that subject is studying people who have experienced this. Some things we want to understand our only option it to take it on faith.
