Well...
This gallery is interesting and disturbing, but mostly thrilling.

That spider is way bigger than anything ever needs to be.

Picture #1 was probably adapted from the many hooked mouth of the lamprey.

Base +10, Bulcon +7, Anus Nightmare -5, JikanPie +7

The people that down voted this are no fun. Nothing wrong with some original creepiness now and then.

This is one creepy **** right here... O_o

I clearly see that artist based on paintings made by Zdzisław Beksiński or at least, has similar style. Check Wikipedia or google for it. Expect mindfuck.

Well i .. pretty mutch like how the shadows fall (really deep & monopolozing)but dont disturbing the wanted main attention ..even if it´s questionable to look at it before going to sleep ! Not my genre.. but good drawing !

It's sort of interesting trying to see what references the artist is making with each picture. On the other hand, that kind of takes away the suspense of disbelief and makes these pics more homage or parody.

Base +11, ggggehent +9, Generika +15, Paizurikin -7, salcon +4, Anus Nightmare +5

Interesting concept really

Base +6, Paizurikin -7, Surly1212 +5, Romi the Byzantine +6, Anus Nightmare +5

Creepy but the pictures draw you in

Base +8, ggggehent +9, Generika +15, Paizurikin -7, Surly1212 +5, Anus Nightmare +5, George642 +8, faytT +8, Sturmjager +9

A little eldritch horrors now and then drain the san from the wisest men. Seriously though this some Lovecraftian stuff right here.

Favorited.

How is this Hentai you asked ??? Cause it's freakin NON-H that's why =P

Base +6, Anus Nightmare +5, George642 +8, vincenth93 +6, CARAGE +6, lavajava12 +5, FreeloaderEX +6, byehi +6

Glad these didn't make the cut in Monster Girl Quest.
Interesting nonetheless.

Base +6, Anus Nightmare +5, George642 +8, faytT +8, enkithemighty +2, admiraltolokus +7, J5IsAlive +2

It's okay, I didn't need to sleep anyway.

A, e-hentai: come for the porn, stay for the fascinating weirdness! Incidentally, thanks to @LittleSweetLoli for bringing Zdzisław Beksiński's work to my attention. Different and so bizarre...

Base +6, Anus Nightmare +5, faytT +8, Shinryu-Rex +5, Wossname +6, tony34 +5

The creepiness of the first pic draws you in. While I'm not big on guro, the artwork is awesome.

Oh yeah, and just plain creepy.

Base +24, Anus Nightmare +5, fallicious +7, George642 +8, Otaku_King +6, Acerola +10, shadow king +6, Romi the Byzantine +6

Very nice, so glad I was linked to this.

Base +6, joubert -6, White Joker +13

I think someone just posted a children's book from the Berserk universe.

Base +6, White Joker +13

..........#69 kind of looks like a vagina.

That Mami.

Base +6, wanna +20

This guy is amazing in a very horrifying way.

Base +8, JikanPie +7

I actually found this to be amazing. Ty for sharing an awesome artist

Base +7, tony34 +5

.... Perfectly fitting into the Non-H section. I don't wanna fap now. Thank you so much...

[Edited]
P.S. but you know what, when I keep staring at those pics for about ten minutes, I started fapping.

Favored.

Base +6, tony34 +5

Beautiful and inspirational. I love this.

Base +6, tony34 +5

Not bad, quite tame actually compared to most other guro other there, but I'm a genuine sucker for creepiness.

Base +6, tony34 +5

pic 1, dem blowjobs must be rough yo

Base +5, White Joker +13, tony34 +5

Defintaly Silent Hill style in some pics

Base +6, Carla Sweet +9

interesting, it's original...

Base +5, White Joker +13

@supermantis : pray tell me what was the strangest thing you found on this site?

Base +11, floobadeedoo +6, Shinryu-Rex +5, rakies +8, tony34 +5

Reminds me a lot of Yume Nikki. Especially the buildings and other square-shaped structures.

Base +10

nothing like a little mindfuck to start the day

Base +6, tergviteza +6, dexetus +6

Incredible artwork. Reminds me Zdzisław Beksiński 5/5!!!

Base +7, tomato86 +10, Necronomicron +7, JikanPie +7

Page 85 - I don't want this bride to turn around O_o

Base +6, tony34 +5

I don't mind guro galleries, it's just hentai after all. But the first picture in thumbnail view mode creeped me out. Next time, please choose a less grotesque image for the first image - though I understand why you'd want a really grotesque image for the first image: to attract other guro fans, because first impressions are important when it comes to hentai - or choose an image that acts as a cover warning for the gallery, something like "Warning: Guro!"

Base +8, Allhazard +6, sumielumie +5, Briorius +7, JikanPie -7, tony34 -5

Not bad. Although I have seen worse, this gallery looks extremely macabre and grotesquely horrifying that it draws you in. I expected Pixiv artist to be close to any genre in anime, even if it's guro but this artist is definitely amazing and downright unique, in a brutally nightmarish manner. Really hope to see more from him/her.

Base +6, tony34 +5

I like 56 for strange reasons unknown to me...

Base +7, samael101 +4

Perfect for a dearth metal album cover.

Base +9, tony34 +5

Perfect for a death metal album cover.

Base +9, tony34 +5

Sigh.. Unzips pants.

Base +7, Marogareh +7, IceGolem +6, tony34 +5

精神污染意外带感

Base +20

Looks like someone's just in time for Halloween!

Base +10

Challenge accepted!

Base +10, Anduin91 +8

But those lamps though....

Base +6, Shinryu-Rex +5

Well, I think that's enough masturbating for tonight. Or eternity. However long it takes me to recover

Base +6, tony34 +5

Looks like someone played Bloodborne.

Base +6

Pic 1 - Monalisa Of The Damned!

精神污染……艹尼玛一点都不带感啊！！

I cant stop thinking of Welcome To The Machine now.

I wanna put my dick in it.
