Not sure about Sleep Paralysis, but I know of a theory which proposes why we dream of horrible events. It is built on the assumption that the purpose of dreaming is to provide a threat simulation system, in which we can safely rehearse threat recognition and threat avoidance so that we may be better prepared to face such threats in reality, whether to fight them, or to flee, but in the broadest sense, to ensure our survival and reproductive success.
This theory was proposed by Antti Revonsuo (2000), and as you can probably guess by my description, it is an evolutionary theory. The source of such a system supposedly comes from the enormous amount of time mankind has spent living in the wild, when battles between life and death with predators were much more common. A highly emotionally salient encounter during the day, such as a situation when your life is genuinely threatened by a predator, will likely re-emerge later that night in a dream, because the memory trace is stronger, due to both emotional salience and recency. Because evolution is such a slow process, and because we have only recently begun living in safer environments like houses (as far as human history is concerned), the threat simulation system still exists even though the threats we face today are entirely different. If we live in an environment where there are very few or no threats, the threat simulation system will become dormant until a threatening encounter triggers it again. When it is dormant, we will dream about what is next emotionally salient, namely our current concerns and worries.
Again, I'm not sure how to apply this to sleep paralysis; from my own few experiences of SP, I remember nothing disturbing happening.
Hope that sheds some light on your question.
