Are powerful near-death experiences real or simply New Age fiction? Now a large-scale study aims to find out. Clint Witchalls and Michelle Hamer report.When Sylvia Cameron was a young mother in the 1970s, she had never heard of near-death experiences and gave little thought to what might happen after death. But at 29, the Melbourne volunteer trauma counsellor almost bled to death after her uterus ruptured from the complications of an ectopic pregnancy. While doctors struggled to save her life she experienced something she could not explain. "I remember looking down on my body on the operating table. It was a very hot day and the doctors were in their shorts and sandals with their aprons over them," says Cameron. "I was surprised at all the blood everywhere and slightly horrified at the conversation going on between the staff. "The gynaecologist was giving me a heart massage, thumping my chest and saying: 'Don't you die on me now you bitch' and I was quite shocked. I thought, how dare you speak to me like that. "Then I felt that I was drawn down a vortex or a tunnel and I could see this light at the end of the tunnel and I could see people standing there, but because the light was behind them I couldn't see any faces. It was all very natural, I wasn't frightened. "I turned my back on these people and said 'I don't want to come yet'. I felt I had too much to do; I felt I wasn't ready for that — whatever it was. When I woke up I was back in the recovery room." After getting a negative response from the few people she told, she pushed the experience to the back of her mind.
