I knew a bipolar patient who believed he was a shaman. In his last manic episode he was found wandering outside naked in minus twenty temperatures. He said he had transcended to a higher consciousness where the cold no longer affected him.

I interviewed him a few months later to see if he was taking his medicine. He was, but said he didn't like the medicines because they took away his special powers.

He had frost bite on his hands and feet from the incident by the way.
