Good to see another writer! As for Cosmic Horror, also known as Lovecraftian Horror, is a subgenre of horror that focuses on humanity being insignificant in the cosmos and the horrific beings that roam it. The genre was said to be created by H.P. Lovecraft.
Here's a link that contains more information about it.

Awesome, and on one hand, you have people taking selfies, and then you have insignificientism and smallness on the other hand. Thanks for the link. Interesting. I might try to be balanced in the middle of two extremes. But a focus on anthropology, maybe on depravity, is a healthy thing to do. A lot of exploration there that helps.
I wish you luck on your endevor!
