Dr. Eben Alexander's Heaven Experience

Recently, I was walking down the magazine aisle at the grocery store when I chanced upon Newsweek magazine and the article, "Heaven is Real: A Doctor's Experience with the Afterlife".
It's not often that you see a scientist proclaim experiences such as this, and the experience that he had while in a coma is fascinating and breathtakingly beautiful. It was only after I searched online about it that I remembered that I'd seen Dr. Alexander's tale on "Through the Wormhole" (a show on the science channel, narrated by Morgan Freeman). He has published a book about his experience called Proof of Heaven that I'm anxious to read. Have you ever had an afterlife experience or do you know someone who has?
