A man, Martin Pistorius, who slipped into a coma aged 12, has revealed the living nightmare of waking up from the coma only to find out that he was unable to move or communicate or do anything for himself for 12 years. And to his horror, when he did awake, he was unable to communicate his return. The South African man was diagnosed with a debilitating form of meningitis in the late 1980s and was left unable to move, speak or even make eye contact.
