I really like the thumbnail you used. Too bad I won’t be dressing up this year :(.
I do have suggestions for you to watch if you are interested. Kind of like Highschool of the Dead, you should see Rosario Vampire. Another anime I recommend that’s creepy and weird is Durarara!!. Durarara!! is an anime where anything is not normal and the people are not normal. You have gangs, a headless rider, Russian agents and Yakuza gangs. Overall you have to ask yourself this, how would you feel if everyday was weird to the point where weird things are normal.

I still need to watch Soul Eater and Ouran High School Host Club. I dropped Soul Eater a long time ago
