I think perspective on the unsolvable problem of death is a core component of personality. I have only seen a handful of theories about HPD and death perspective, or thanatocentrism, if you will.

Somewhere I read that hysterics have been noted as not understanding death, killing themselves because they know they will be the center of some people's worlds for a time.

The way the text actually said it, however, is that the hysteric thinks they can attend their own funeral. Ha ha ha.

I think it's less pleasure-seeking than that. It's security seeking. I don't think I've ever wanted to be a person. I want to be a static concept. Death is the only way to achieve this, except for fame. When a hysteric dies, they effectively become an immortal situation. The catch is that, as far as we know, the hysteric will not be able to reap this ultimate wage for the ultimate chore.

I think histrionics are human expressions of the white rabbit in Lewis Carroll's works. We compensate for self-doubt by rousing others into revealing the demons in their closet. We absorb these demons and leave the now exercised person and go exercise these demons, giving them to others.

The histrionic is the fury or the harpy or the white rabbit. They are messengers of fate, and carriers of punishment.

Of course, that's based on introspection alone so it might not be relevant.
