It's hard to listen to accounts of people who've had [near-death] experiences and not be moved. Leanda Pringle from Connecticut had a NDE a little over 15 years ago, brought about by a double kidney infection. She experienced floating above her body and felt a sense of being everywhere and nowhere at the same time. "I've no idea how long I was floating in that abyss before I began to feel a presence," she recalls. "As it got closer I began to feel immense bliss. It was beyond anything I had ever felt before in my life. It's very hard to put that feeling into words. It was as if I was intertwined with it, but at the same time it felt as if it was hugging me." Tommy McDowell, a retired army veteran from Texas, spent seven days on a ventilator after suffering multiple organ failure induced by sepsis. During that time, he had a NDE that involved feeling a powerful sense of goodness. "It was a transformational presence of peace, comfort, serenity, love and home," he says. "I was no longer confused. I was no longer alone." He also saw a cloud of crystallised light that invited him towards it. As he entered, "I could feel embedded trauma, regret and loss washing away from my back and shoulders." Reflecting on what happened, Tommy says, "I experienced the presence of God. It was overwhelming and occurred in a way that I just don't have language to fully describe." By now, scientists have collected thousands of similar testimonies from people who have lived through a NDE.
