The Belgian former engineering student, who speaks four languages, said he coped with being effectively trapped in his own body by meditating. He told doctors he had "travelled with my thoughts into the past, or into another existence altogether". Sometimes, he said, "I was only my consciousness and nothing else".
Words probably can't describe what that must've been like... I wonder, since he's just been using his brain for the past 26 years, if he has developed some certain... abilities? idk
