I just watched this last night and was completely blown away and think some of you guys might be as well. It basically goes into psychics, premonitions, after death experiences etc. One "psychic" is clearly a fraud but they do have some really compelling stuff.
Most interesting of all was the Harvard educated Neurosurgeon who had an after death experience and was a non believer prior. He instantly became a believer in life after death and God upon waking. He wrote a book before even telling people because he didn't want to face huge back lash (being renowned in his field and all).
The most common explanation for after life experiences is that the brain generates these images automatically but the meningitis he had in his brain was so severe that he was practically brain dead during the 7 day coma before overcoming all odds and making a full recovery.
Something I found interesting as fu** was... the beautiful woman who was guiding him in this heaven ended up being his sister that he never met! He got a photo sent to him by his parents a few months after this experience and completely broke down when he realized his "angel" was his sister.
