What happens when you die? It is most certainly one of life's biggest questions.
Several near-death survivors have come forward to narrate what they had a glimpse of when they were in heaven.
Now, Don Piper, an ordained Baptist minister, who was once pronounced dead following a car accident, has shared his intriguing story.
He says he remembers music that was "beyond spectacular" and aromas he'd never smelled before. His grandfather was there to greet him warmly, as dozens of others who had died in years past stood before him in front of a magnificent gate, reports ABC News.
Piper, who insists it was no dream and visited heaven, has chronicled his experience in the New York Times bestseller, "90 Minutes in Heaven." "It was the most real thing that ever happened to me," he said.
There were lights reflecting off the gates, which looked like they were "pulsating with life. "That's because in heaven there is no artificial light, God illuminates it with his glory. In front of the gate stood his grandfather, welcoming him "home," he said.
"I was heartbroken when he died," he said. "Now I'm at the gates of heaven (and) he's the first person to greet me."
Piper, who was ordained in 1985, said he could not have imagined what he saw in heaven. "You know, if I was having a dream about it, this wouldn't be in it," he said. "Some of these people who met me at the gates, I haven't thought of in decades."He believes he was sent back to spread a special message: "Heaven is a real place".
