Except... three of these people aren't actually trans.
Buffalo Bill merely
thought he was trans due to his self-loathing. Hannibal Lecter outright says he's not trans.
"Angela" was forced to pretend to be a girl by "her" lunatic of an aunt.
Norman Bates had multiple personality disorder, with his other personality being his deceased mother.
I've never seen
Dressed to Kill, so I can't comment on that one.
