Kate Allatt was in a coma for three days after she had a stroke in 2010. She woke up with locked-in syndrome, able to think, see, hear and feel, but unable to move or communicate. She was misdiagnosed as being in a persistent vegetative state and it was only two weeks later that friends realised Kate was fully conscious. “It was horrendous,” she says. “It was like being buried alive.” Over the next seven months she staged a miraculous recovery.
