> Once, after injecting himself with a large dose of morphine, he found himself hovering over an enormous battlefield, watching the armies of England and France drawn up for battle, and then realized he was witnessing the 1415 Battle of Agincourt... The vision seemed to last only a few minutes, but later, he discovered he’d been tripping for 13 hours.

This doesn't make any sense... morphine is not a hallucinogen or a psychedelic. You don't "trip" on it. I have a feeling the journalist mixed something up here.
