I knew a person with DID once.

She was really destructive.

A former anorexic (or some kind of eating disorder), who claimed to be a Christian, the totally shifted into claiming not to be one.

She seemed to be intelligent, but I see know it was just a bunch of hot air. She confused/scared me at the time.

She claimed to have run her own camp of the OTO, and was obsessed with Jack Parsons.

Claimed to be a demoniac, too - and that she was a wild type of sex with either a demon(s) or even worse.

Took a ton of pills to lose a bunch of weight once.

There's more, but them's the highlights. Or rather lowlights. She really did hurt a lot of people.
