However, just as he was taken into pre-op, Alex is convinced he died.
He said: “My eyes rolled up, the lights went out and my last thought was, ‘Thank God, it’s over!’
“I was then aware of being in blackness, with absolutely nothing.
“Then I felt such intense happiness, joy and love. There are no words that can really express what I was feeling”
Alex compared the experience to seeing the world through a curtain of fog.
As it became clearer and more in focus, he began to see human silhouettes bustling around someone lying next to him.
