Nah, I don't think so.

About that doctor who claims that while he appeared comatose, he was actually spending time in the afterlife, I wonder how much experience he's had with drugs.  As a medical professional, he must have benefitted from a number of sensory-altering painkilling drugs in his lifetime; wouldn't you think he would at least suspect that while he was being treated for such a devastating affliction, he would be loaded up with a variety of drugs that would cause him to hallucinate, especially combined with his own body's attempts to respond to the trauma he was enduring.  I myself have had very limited exposure to drugs of any kind, but I do know that they affect your sense of reality, because in actuality you are not in the same dimension as before.   You wouldn't know that if you were truly unconscious, or comatose, but at that stage in between, you're not living life as you knew it pre-drug, but you're certainly not dead either, and therefore not entitled to join the afterlife.  In the last few months, I've been under some degree of anesthesia on three separate occasions.  Each of them brought a sense of altered reality, a kind of afterlife, if you will.   One drug  administered allowed me to ascend above  the norm, and restructure the universe, using all my talent and wits, with the world being my own, and I the great benefactor and beneficiary of all that I managed to bring about.  I would  prefer to think of that feeling as the afterlife I'm destined for, but I think that would just be a self-indulgent ego trip on my part.
