Harvard neurosurgeon 'visited' heaven after near-death experience

Dr Eben Alexander is now telling the world that heaven is real and afterlife exists in his new book, Proof of Heaven. Alexander, a Christian, claims he took the journey to the afterlife when he slipped into a coma in 2008 after contracting a very rare bacterial meningitis.

Alexander describes the heaven he saw over the course of seven days in a coma in an article. "Toward the beginning of my adventure, I was in a place of clouds. Big, puffy, pink-white ones that showed up sharply against the deep blue-black sky," he wrote.

Alexander said that he travelled through this heaven, surrounded by millions of butterflies, with a woman. After the neurosurgeon awoke from the coma, he penned the book, Proof of Heaven. u00a0 u00a0 u00a0u00a0
