I smelled a guy that did that once. 1991. Amherst, MA. Was going to Hampshire College. Still have newspaper clipping.
A guy self-immolated in protest of Iraq.
Even though the college was in the woods and miles away from the center of town where he did it, the light blue smoke and the sickly sweet honey smell covered the campus that day.
Since I learned about spontaneous combustion from TV shows of ‘weird things in the 80s, I knew exactly what it was even before I knew a guy set himself on fire.
Very surreal… breathing in a guy.
2nd time was 9/11. 5-10 miles away as the crow flies in New Jersey. That was mixed with burnt concrete smell. Just as gross.
