[F] wanted for psychological smut horror

Greetings to you, devious ones

Recently I came across some interesting piece of entertainment that resonated with some twisted ideas that were lingering somewhere inside my mind. And those ideas shaped the thriller / horror narrative discussed in this thread. If you have some familiarities with the Silent Hill series, the phychological horror and grotesque imagineries chances are you might even enjoy yourself reading through this.

KEY WORDS

Your character against the world

A journey through a reality wrapped into a nightmarish scenario

All horror elements are derived from the human mind, and its perversions

Sexual cravings become manifest and become a threat

Powerful contrasts between determination/threats and beauty/horror

SUMMARY

The story would follow one female character - who I leave in your capable hands - that is following a disturbing trail of incidents and mysterious reports. She doesn't necessarily have to be a police detective on official duty, but still have strong reasons to see the ordeal through.

Since your character is pretty much the sole protagonist, I would be very interested in discussing unique aspects, perks and any peculiar personality trait that would make her more interesting or just add meaning to her motivation and backstory. She is meant to carry the emotional weight of such horrific journey so she has to appeal to both writers while moving things forward.

Every other character - and creature - would be handled by my own writing. The narrative being structured like an investigation that spirals down into the unknown would require your character to interact with different ones, even if only once, and make choices regarding how to approach any kind of threat. For that reason, I would see the story focus never leaving your protagonist and only involve other character when it calls for them. 

The time frame is modern - not necessarily 2022 but anytime from the 90s to today. It would be actually pretty interesting to discuss the role of communication devices such as cell phones or computers. 

The setting would first introduce a "real" location but the shift to its supernatural, twisted version populated with things that cannot be explained. It would appear like the classical "descent to hell" but without any actual traveling to firey caverns or such. The character would still explore modern environments but they would be heavily altered with elements such as deep fog, disturbing noises and - most of all - horrific dwellers. The reason behind everything that happens being both psychological and supernatural, also based on your own tastes.

The threats surrounding your character would be derived from the humand mind, like if sexual depravities and uglinesses took form and infested the place. They would still look human, but could push their visuals to grotesque takes on the human bodies. There would be no gore or strong violence but instead the representation on unchained sexual urges, craving for your character body and pleasure, trying to corrupt her mind and bring her down.

How would your character react to everything that's happening around her? Not just from a rational point of view, looking for clues and a way out, but more importantly from an emotional and irrational one, having to deal with reflections of her own desires or disgusting variations of the things herself might crave...
