Dr. Linda Kramer recounts her extraordinary experience of being clinically dead for 15 minutes and her vivid recollection of spending five years in heaven. On May 6, 2001, as she went to the toilet in the early hours of the morning, she felt as though she was going to sleep, but instead, she embarked on a journey beyond this world.

Her experience, though brief in the physical realm, was a profound and enlightening one, forever etching the memory of the afterlife in her mind.

She would later discover that she had been pronounced medically dead for almost 15 minutes, but in that time while she was being treated by paramedics, she said she felt like she’d been in heaven for five years.

Since ‘time did not exist’ as we would perceive it, she said she would estimate the passage of time depending on how far she had travelled through this world she now found herself in.

Guessing that she could walk at a rate of about three to six miles per hour in real life, she used that to chronicle time as she moved around heaven.

Dr Linda found that she could assume any form she wanted in this domain and could even become other people she met in heaven, and the place itself was full of striking visuals.

She said: “That’s when I found myself standing in what I termed the the field of flowers. I was observing the mountain range 30,000 times huger than Mount Everest.

“There’s a huge mountain range over in the back of wherever I was. I could see buildings with skyscrapers. Dubai are like little miniature huts in comparison. I saw lakes, I could see everything in a panoramic view.”

“So I’m there interacting with people, talking to people, becoming them.”

If she wanted to be somewhere, she thought about being there and felt instantly transported to that place, able to appear atop mountains and other locations seemingly at will.

Others who have been clinically dead for a period of time and come back claim to have seen visions of the afterlife, with one woman writing out the message ‘it’s real’ and pointing up towards heaven.

Another man says he met the devil after being stabbed in the heart before being dragged out of hell by an angel after praying for the first time in his life while doctors fought to save him on the operating table.

However, a scientist has said that life after death just isn’t possible as consciousness persisting after death is pretty much impossible, meaning that once you’re gone for good that really is the end.
