60-year-old Tom Kennard was suffering from sepsis after surgery for cancer.
In his hospital ward, Tom collapsed and became unconscious for three hours.
He said he "floated upwards to the top of the room. I looked down and I could see my body on the bed. It was lovely, so peaceful - and no pain at all."
He entered a pink room, met a man with kind eyes, and met his father and talked telepathically with him.
He saw the nurse putting a swab into his mouth to clean it.
He could also see a woman beyond the cubicle curtains.
Tom also found that right hand, which had been stuck in a claw-like position since birth, was mysteriously cured.
Fred Williams, in his 70s, had a terminal heart problem.
One night in hospital, he lost consciousness.
When he regained consciousness some time later, he looked very happy.
Fred told his relatives that, while unconscious, he had been visited by his mother, grandmother and sister, all of whom were dead.
"Suddenly, in the distance, I heard my eldest daughter shout, 'Mam'. I remember thinking, 'Oh dear, Jacquie needs me,' and I came back with a jolt.
"I’m not a religious person but I believe there's a warm, peaceful, beautiful place after death."
